It has been reported that the mammalian corpus luteum is composed mainly of two subpopulations of luteal cells (large and small) of different morphology and function. The aims of this study were first to characterize ...

The differentia] capacity for steroid synthesis of human luteal cell subpopulations was investigated in a well defined cell culture system. Corpora lutea were enzymatically dissociated, and the two cell types were ...

We present a simple non-radioactive cytometry-based assay that permits the simultaneous quantitation of cell adhesion of distinct subsets of cells contained in a mixture without any previous fractionation. The procedure ...

In addition to the T helper 1 (Th1) and Th2 lymphocyte subsets, two new subpopulations Th17 and regulatory T (Treg) cells have recently been described. Th17 cells, which produce high levels of interleukin (IL)-17, ...

Cancer treatments options are limited by the generation of therapy resistance, which is due by intratumoral heterogeneity in cell response. The study of resistance requires biosensors able to report the response at the ...

Any physiological mechanism involved in sperm selection and semen improvement has effects on heterogeneous sperm populations. This is mainly due to the fact that sperm populations within a single ejaculate have considerable ...

Spermatogonial stem cell (SSC) is known for its self-renewal capacity. We have studied the in vitro proliferation of isolated SSC from adult alpaca (Vicugna pacos) testes. A total of 107 samples were evaluated of which 31 ...
