Pluripotent, Lin–/CD45–/Sca-1+ very small embryonic-like stem cells (VSELs) in mouse bone marrow (BM) are resistant to total body radiation because of their quiescent nature, whereas Lin–/CD45+/Sca-1+ hematopoietic stem cells (HSCs) get eliminated. In the present study, we provide further evidence for the existence of VSELs in mouse BM and have also… (More)
We have studied the effects of Pb2+ added in vitro on the movements of Ca2+ in renal cortical mitochondria and tissue slices. The isolated mitochondria rapidly accumulated 45Ca2+ at 25 degrees by a mechanism that was dependent on respiration and inhibited 96% by ruthenium red. A concentration of 10 microM Pb2+ inhibited the Ca2+ accumulation at least as… (More)
Slices of rat kidney cortex were induced to swell by preincubation at 1 degree C in an isotonic Ringer's solution, and their capacity to reverse swelling, by net extrusion of cellular water, was studied during subsequent incubation at 25 degrees C. The recovery from swelling was prevented by the respiratory inhibitor, antimycin A. On the other hand,… (More)
Very small embryonic-like stem cells (VSELs) have been reported in various adult tissues, express pluripotent and primordial germ cells (PGCs) specific markers, are mobilized under stress/disease conditions, give rise to tissue committed progenitors and thus help regenerate and maintain homeostasis. The aim of the present study was to evaluate in vitro… (More)
Changes in ciliary ganglion cells are described after the experimental induction of glaucoma in rhesus monkeys. They appear within 12 hours in the form of peripheral displacement or extrusion of the cell nucleus and loss of Nissl granules.
