Summary
Buffalo testes contain stem cells expressing Pou5f1 (Oct 3/4), a key marker for pluripotency. These germ stem cells from young buffaloes show potential for establishing cell lines for genetic modification.
Area of Science:
- Reproductive Biology
- Stem Cell Biology
- Livestock Genetics
Background:
- Water buffalo are vital livestock, with India housing half the global population.
- Developing stem cell technology in buffalo is crucial for targeted genetic improvement.
- Testes are known sources of pluripotent stem cells in other species, but data in buffalo is limited.
Purpose of the Study:
- To investigate the expression of Pou5f1 (Oct 3/4) transcript and protein in buffalo testes.
- To determine the stem cell potential of gonocytes/spermatogonia from prepubertal buffalo testes using a transplantation assay.
Main Methods:
- Semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) to detect POU5F1 transcript.
- Immunohistochemical analysis to localize POU5F1 protein expression.
- Testis transplantation assay in mice to assess stem cell potential of buffalo gonocytes/spermatogonia.
Main Results:
- POU5F1 transcript and protein were detected in both prepubertal and adult buffalo testes.
- Western blot showed two POU5F1 protein isoforms (∼47 kDa and ∼21 kDa) in buffalo testis.
- Immunohistochemistry revealed POU5F1 in prepubertal gonocytes/spermatogonia and adult post-meiotic germ cells, with stem cell potential confirmed by xenotransplantation.
Conclusions:
- Prepubertal buffalo gonocytes/spermatogonia express POU5F1 and possess stem cell potential.
- These cells represent a promising target for establishing germ stem cell lines in buffalo.
- This could facilitate future genetic modification strategies for this important livestock species.

01:41Spermatogenesis
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...
01:22Spermatogenesis
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...

01:06Multipotency 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...
00:58Embryonic 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.
00:57Embryonic 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...

01:27Source And Potency Of Stem Cells
Stem cells are undifferentiated cells with extensive self-renewal properties that help them maintain their population during the fetal and adult stages of life. They can specialize in all cell types of the human body. However, their differential potential may vary and can be classified into five types. Stem cells can be (1) Totipotent, (2) Pluripotent, (3) Multipotent, (4) Oligopotent, and (5) Unipotent. Each stem cell has a specific origin; the fertilized egg or zygote is a totipotent cell and...
