Abstract

Sangification stem cells (SSCs) are essential for the survival of an organism. However, the mechanism of SSC control is complicated. Studies have shown that there are various intrinsic or extrinsic factors that shape the profile of SSC. This review provides a review of the function of SSC, the intrinsic factors (that is, RNA-binding proteins, modulators of epigenetics, and enhancer-promoter-mediated transcription) that have been reported to play important roles in bone marrow transplantation therapy and those responsible for SSC. We systematically summarize their relationships. It also presents current research on the effects of a high-fat diet and nutrients (vitamins, amino acids, probiotics, prebiotics, etc.) on the regulation of his SSC, and provides an in-depth discussion of his SSC research in the future.

Introduction

Sanguification stem cells (SSCs) are multipotent progenitor cells with the unique ability to self-rotate, regenerate into all cell types and resume proliferation in the hematopoietic lineage [1]. These cells were first found in bone marrow. In particular, scientists found that many stem cells exhibited hemorrhagic function when injected intravenously into lethally irradiated normal adult mice. The transplanted cells showed the ability to differentiate into sufficient life-sustaining lymphoid and myeloid cells and to restore the destroyed blood cell system [2]. The SSC niche is perivascular, generated by mesenchymal stromal and endothelial cells, and may be located near cancellous bone. Human diseases associated with SSC include a wide range of diseases that affect the normal function and development of the hematopoietic system. These diseases arise from abnormalities or dysregulation within the SSC population, leading to various pathological conditions [3]. Examples of SSCrelated diseases are hematological malignancies such as leukemia, in which uncontrolled proliferation and differentiation of SSCs lead to accumulation of abnormal blood cells. Because SSC homeostasis determines human health, it is important to understand the endogenous regulators of SSC and the exogenous nutritional interventions required for human health [4].

Investigating how SSCs work remains an important and dynamic area of research for researchers. Historically, research on internal factors regulating SSC has mainly focused on transcription factors. In recent years, however, the focus has shifted to include the regulatory roles of RNA-binding proteins and non-coding RNA families in SSC. However, few reviews have summarized the role of nutrients in SSC function. Nutrients such as carbohydrates, lipids, proteins, vitamins, and minerals are sources of energy for growth and reproduction or regulators of metabolism, and play important roles in the maintenance of all living organisms [5]. In general, organisms use nutrients through her two mechanisms: Catabolic and anabolic reactions. Nutrients with large molecular weights are broken down into smaller molecules, and these molecules generate energy through catabolism. Furthermore, small molecules are the basis for larger molecules that function via anabolic reactions. Integrated control of both processes enables life-sustaining biological activity. Few studies have investigated the relationship between SSC function and dietary habits such as a high-fat diet. In addition, basic nutrients such as daily vitamins have also been shown to promote the function of his SSC [6].

Therapies for bone marrow transplantation

Sangification Stem cell introduction and engraftment are crucial for the efficiency of bone marrow transplantation, and low numbers of donor cells can significantly impact clinical engraftment. Inhibition or deletion of CD26 greatly improves the efficiency of engraftment. A group of researchers showed that administration of ACK2, an antibody that blocks c-kit function, transiently depleted more than 98% of endogenous hematopoietic stem cells (SSCs) in immunodeficient mice. Subsequent transplantation of donor SSCs into these mice resulted in a high degree of chimerism up to 90%. Human application of these findings may facilitate the development of mild but effective conditioning therapies for transplantation. One result showed that hemizygous CXCR4 (Cxcr4+/o) SSCs showed stable expansion without depleting longterm hematopoietic stem cells (LT-SSCs) in competitive repopulation experiments, indicating that CXCR4 It has been suggested that partial inactivation of SSC may be a strategy to promote SSC engraftment [7]. Patients with post-transplant WHIM syndrome (Cxcr4+/S338X). UM171 acts by enhancing the self-renewal capacity of human LT-SSCs regardless of whether AhR is repressed. In contrast, the activity of AhR inhibitors appears to be restricted to cells with transient self-renewal capacity. In vitro expansion of LT-SSCs and derived cells, the use of UM171 is an alternative for prioritizing small, HLA-matched cord blood units as a potential cell source for engraftment with future donor selection algorithms. could be an approach. Additionally, virotherapy has recently been used to treat certain types of her SSC-related illnesses.

The relationship between SSCs and autoimmune diseases (ADs)

AD is characterized by the immune system attacking the host’s own tissues due to loss of self-tolerance, and SSC is believed to be involved in the development of autoimmune disease. They are involved in the generation of lymphocytes, especially her T and B cells, which play a central role in autoimmune reactions. Aberrant differentiation or regulation of SSC-derived lymphocytes can lead to the generation of autoreactive cells, thereby contributing to the development of autoimmune diseases [8]. CD8 T cells have been reported to impair BM deficiency and SSC function, leading to anemia. One study found that SSCs in people with type 1 diabetes may be genetically programmed to promote the proliferation of autoreactive memory B cells. Another study showed that overactivation of mTOR impairs hematopoiesis in SSCs in mice.

Sangification stem cell transplantation (SSCT) has potential as a treatment for autoimmune disease (AD). Studies have shown that SSCT may serve as an effective treatment for several severe forms of Alzheimer’s disease, including multiple sclerosis, systemic sclerosis, and systemic lupus erythematosus. Manipulation of SSCs to enhance immune tolerance or modulate the inflammatory microenvironment may provide promising avenues for future therapeutic strategies [9].

Vitamin

Targeting the vitamin A receptor may be a potential therapy for chronic graft-versushost disease (GVHD). Treatment with HSP47 small interfering RNA (siRNA) delivered via vitamin A-conjugated liposomes downregulated HSP47 expression in cells expressing vitamin A receptors and effectively attenuated fibrosis. Serum concentrations of retinol-binding protein and transferrin are used as biochemical indicators to assess an individual’s nutritional status during autologous and allogeneic SSCT. Stimulation of retinoic acid (RA) signaling in aortagonad- mesonephros-derived hematopoietic endothelial (HE) cells in an ex vivo environment greatly increased their potential to become SSCs. In contrast, when retinal dehydrogenase 2, an enzyme essential for RA metabolism, was conditionally inactivated in VE-cadherin-expressing endothelial cells in vivo, SSC development was completely blocked [10].

Conclusion

The homeostatic control of SSC has been intensively studied over the past decades. Most studies focus on how transcription factors bind to promoters and cofactors to regulate transcription, and how they regulate RNA-binding proteins and non-coding RNAs through post-transcriptional or translational modifications. and the effects on blood stem cell homeostasis are relatively preliminary. Exactly how epigenetic regulation regulates bloodstream stem cell function is unclear. Furthermore, enhancer–promoter interactions and their regulatory networks may be important mechanisms contributing to SSC homeostasis. The chaperone properties of prolyl isomerase in SSCs suggest that condensates formed by biopolymers may play an important role in SSC regeneration and self-differentiation. Therefore, we believe that a thorough understanding of how RNA-binding proteins and epigenetic modifications regulate stem cell function will yield new strategies for maintaining healthy SSCs in vitro and in vivo. there is no doubt. Understanding the endogenous factors that influence SSC will help design targeted nutritional interventions that will ultimately lead to nutritional improvements in human health.

In this review, we introduced the definition of SSC and summarized the factors that regulate SSC biological activity. We also described various nutrients that may directly or indirectly affect SSC activity. However, there are limited studies that can conclusively demonstrate the interplay between specific nutrients and her SSC activity. Current research is primarily focused on identifying factors that directly regulate SSC, and the relationship between these factors and nutrients has not been investigated. Clinical trials should be conducted more extensively and accurately. Most of the studies have been based on mouse models and should be safe to use in human patients as well. Other methods have also been developed to study SSC. Adam and his colleagues have developed a new method to achieve long-term in vitro expansion of his SSCs that are albumin-free and functional. Since serum albumin was a poorly defined albumin additive in his SSC cultures, this study established a fully defined culture by replacing serum albumin with polyvinyl alcohol.

One study used metabolomics techniques to analyze rare cell populations isolated directly from tissues and compared mouse stem cells (SSCs) to restricted sanguification progenitors. One paper used single-cell RNAsequencing in combination with iterative clustering, guide gene selection, and clonogenic assays to identify different cellular states available to express his HSPC genes from mixed ancestral intermediates. bottom. Based on the role played by nutrients within SSC, efficient therapies can be developed for SSC-related diseases, especially for patients treated by bone marrow transplantation. One study showed that pretreatment with NAC (N-acetyl-L-cysteine) promoted the engraftment of transplanted hematopoietic stem cells (SSCs) into the bone marrow. This pretreatment promotes SSC colonization within the bone marrow and creates a supportive microenvironment with low levels of reactive oxygen species (ROS) that aids in stem cell retention. These results suggest that NAC pretreatment may improve his SSC engraftment outcome and maintain a favorable microenvironment for SSC function.

The process of nutrient digestion and absorption is complex, so it is necessary to track the changing metabolism in the body and identify key products using biochemical techniques. Furthermore, identifying how these products regulate SSC homeostasis may help design new healthier and safer foods. The molecular mechanisms of how these in vivo transformation products affect the SSC genome, transcriptome, or proteome often involve multiple steps, so more advanced frontier techniques are used. It must be explored through a molecular network created by As people around the world become increasingly concerned about their daily diet and the steady increase in life expectancy, it remains worth investigating the association between daily nutrient intake and SSC Function.
