Pulsed Feedback Defers Cellular Differentiation [PDF]

PLoS Biology, 2012
Environmental signals induce diverse cellular differentiation programs. In certain systems, cells defer differentiation for extended time periods after the signal appears, proliferating through multiple rounds of cell division before committing to a new ...

Cryo-derived plants through embryogenesis showed same levels of vinblastine and vincristine (anticancer) in Catharanthus roseus and had normal genome size

Scientific Reports, 2022
Cryopreservation of rare plant materials is an important approach for preserving germplasms and is a good added concept to tissue banking. The preservation of embryogenic cell suspensions is even more valuable as the tissues facilitate in producing ...

Mesenchymal stromal cells derived from cervical cancer produce high amounts of adenosine to suppress cytotoxic T lymphocyte functions

Journal of Translational Medicine, 2016
Background In recent years, immunomodulatory mechanisms of mesenchymal stem/stromal cells (MSCs) from bone marrow and other “classic” sources have been described. However, the phenotypic and functional properties of tumor MSCs are poorly understood.
