The origin of immunoglobulin on the surface of TDL in the rat has been studied by comparing the binding of purified alloantibodies recognizing the Ig-1a allotype of rat light chain, with that of rabbit antirat Fab antibodies. Both reagents labeled all TDL from rats of the DA strain (Ig-1a) with two categories of cells being detected; one binding 100-2,000 molecules of antibody, the other 10,000...

We investigated nucleotide-labeling patterns during ongoing hair cell regeneration in the avian vestibular epithelium and during drug-induced regeneration in the avian auditory epithelium. For utricle experiments, post-hatch chicks received an injection of bromodeoxyuridine (BrdU) and were allowed to survive from 2 hours to 110 days after the injection. Utricles were fixed and immunoreacted to ...

Background: Mesenchymal stem cells (MSCs) can be used to treat premature ovarian failure (POF). Different methods have already been applied to detect MSCs in tissues. This study aimed to investigate the quantitative distribution of CM-DiI-labeled human umbilical cord vein MSCs (hUCV-MSCs) in different regions of the ovarian tissue of the cyclophosphamide ( CTX )-induced POF in mice. Methods: Ad...

Cell tracking could be useful to elucidate fundamental processes of cancer biology such as metastasis. The aim of this study was to visualize, using MRI, and to quantify, using electron paramagnetic resonance (EPR), the entrapment of murine breast cancer cells labeled with superparamagnetic iron oxide particles (SPIOs) in the mouse brain after intracardiac injection. For this purpose, luciferas...
