Derivation and morphological characterization of mouse spermatogonial stem cell lines

Derivation and morphological characterization of mouse spermatogonial stem cell lines.

Spermatogonial stem cells (SSCs), having yet to possess decisive markers, can only be detected retrospectively by transplantation assay. It was reported recently that mouse gonocytes collected from DBA/2 and ICR neonates propagated in vitro. This cultured germ cell, named the germline stem cell (GS cell), produced functional sperm to make progeny when transplanted into recipient mouse testes. H...

In Vitro Derivation and Propagation of Spermatogonial Stem Cell Activity from Mouse Pluripotent Stem Cells.

The in vitro derivation and propagation of spermatogonial stem cells (SSCs) from pluripotent stem cells (PSCs) is a key goal in reproductive science. We show here that when aggregated with embryonic testicular somatic cells (reconstituted testes), primordial germ cell-like cells (PGCLCs) induced from mouse embryonic stem cells differentiate into spermatogonia-like cells in vitro and are expanda...

Increase of Proliferation and Colonization in Mouse Spermatogonial Stem Cell by Low Intensity Ultrasound

Background  Spermatogonial stem cells (SSCs) are the foundation of spermatogenesis. Sound wave especially low intensity ultrasound (LIUS) can be effective on increasing the number of cells. In this study we investigated the effect of LIUS stimulation on mouse SSCs proliferation and colonization. Methods: Isolated SSCs from neonate mice cultured in DMEM culture medium with 10% Fetal Bovine S...

Derivation of embryonic stem cell lines.

Derivation of human embryonic stem cell lines.

Human embryonic stem cells (hESC) are undifferentiated cells derived from an early embryo that can grow in vitro indefinitely, while retaining their capability to differentiate into specialized somatic cell types. Over the last decade there has been great interest in derivation and culture of these cells, as they can potentially provide a supply of readily available differentiated cells and tis...
