Abstract

Insights

Spermatogonial stem cell transplantation shows promise for restoring fertility in cancer survivors. Research is advancing the in-vitro propagation of these cells for potential clinical use in fertility preservation.

Area of Science:

  • Reproductive Biology
  • Stem Cell Research
  • Oncology

Background:

  • Gonadotoxic therapies for childhood cancers can impair adult fertility.
  • Advancements in cancer treatment lead to a growing population of adult survivors.
  • Fertility preservation is a significant concern for these survivors.

Purpose of the Study:

  • To review developments in spermatogonial stem cell (SSC) research.
  • To explore the potential utility of SSCs in fertility preservation.
  • To highlight recent advancements in human SSC propagation.

Main Methods:

  • Review of current scientific literature on spermatogonial stem cells.
  • Analysis of in-vitro propagation techniques for human SSCs.
  • Evaluation of animal model studies for SSC transplantation.

Main Results:

  • In-vitro propagation of human SSCs from testicular biopsies has been achieved.
  • This marks the first successful in-vitro propagation of human SSCs.
  • Previous success in animal models demonstrated SSC regenerative potential.

Conclusions:

  • Spermatogonial stem cell transplantation is moving from theory to potential clinical application.
  • Successful transplantation in animals suggests therapeutic potential for humans.
  • Further research is ongoing to ensure the safety and efficacy of SSC transplantation for fertility restoration.

Spermatogenesis01:41

Spermatogenesis

Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male reproductive...
Spermatogenesis01:22

Spermatogenesis

Spermatogenesis is a complex process that involves the development of sperm cells from undifferentiated stem cells in the seminiferous tubules of the testes. The process is essential for the production of mature and functional sperm cells that are capable of fertilizing an egg.
The process of spermatogenesis can be divided into mitosis, meiosis, and spermiogenesis. During mitosis, the spermatogonia or stem cells divide to produce two identical daughter cells, type A and B spermatogonia. Type-A...

Embryonic Stem Cells

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

Embryonic Stem Cells

Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.
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...

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
Somatic cells are...
