Multipotency and Niche of Bulge Stem Cell01:06

Multipotency and Niche of Bulge Stem Cell

A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...
Testosterone: Functions and Regulation01:26

Testosterone: Functions and Regulation

The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...
Adult Stem Cells01:33

Adult Stem Cells

Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously renew...
Stem Cell Culture01:17

Stem Cell Culture

Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...
Mesenchymal Stem Cells01:19

Mesenchymal Stem Cells

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their access...
Stem Cell Therapy for Tissue Regeneration01:21

Stem Cell Therapy for Tissue Regeneration

Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Area of Science:

  • Reproductive biology
  • Endocrinology
  • Developmental biology

Background:

  • Leydig cells are the primary source of testosterone, essential for male development and fertility.
  • Stem Leydig cells (SLCs) are present throughout postnatal life but were difficult to isolate due to a lack of specific markers.
  • Understanding Leydig cell development is key to addressing male reproductive health.

Purpose of the Study:

  • To review the source, identification, and therapeutic potential of Stem Leydig cells (SLCs).
  • To explore the ontogeny of Leydig cells using insights from isolated SLCs.
  • To discuss the implications of SLC heterogeneity for understanding functional differences and environmental impacts.

Main Methods:

  • Review of existing literature on Leydig cell biology and Stem Leydig cells (SLCs).
  • Analysis of cell surface markers for SLC isolation.
  • Examination of developmental origins and functional properties of different Leydig cell populations.

Main Results:

  • Stem Leydig cells (SLCs) have been identified and isolated, providing new avenues for research.
  • Separate SLC pools may generate distinct fetal and adult Leydig cell generations with differing functions.
  • Functional differences in Leydig cells are relevant for assessing environmental pollutant effects, like DEHP.

Conclusions:

  • Isolated SLCs offer insights into Leydig cell development and potential therapeutic applications.
  • Heterogeneity in SLCs may explain functional variations and impact responses to endocrine disruptors.
  • Further research into SLCs is crucial for male reproductive health and understanding environmental impacts.
