The corpus callosum of young rats was examined to clarify the behavior of the three subtypes of oligodendrocytes (the large organelle-rich "light oligodendrocytes," the smaller and more densely stained cells referred to as "medium oligodendrocytes," and the even smaller and denser "dark oligodendrocytes"). It was hoped to find out whether cells of the three(More)
Regional and temporal patterns of the expression of basic fibroblast growth factor (bFGF), and two of its high affinity receptors (FGFR1 and FGFR2), were examined in the male rat brain during early postnatal development; the reverse transcription-polymerase chain reaction (RT-PCR) was used to obtain mRNA measurements which were expressed relative to mRNA(More)
Binaural and monaural ossicle ablation in neonate rats before the time of onset of auditory input resulted in hearing deficits as detected by behavioural responses to sound stimuli in these rats as young adults. Cochlear disruption at the same neonatal age similarly resulted in the absence of startle reflexes in many of the rats. When the middle and inner(More)
The object of this study was to determine whether the oculomotor nucleus and the extraocular muscles are present in the adult of a mutant mouse strain in which eye formation fails early in development (Chase and Chase, '41). Neuronal counts for the oculomotor (IIIrd) nucleus were obtained from serial paraffin sections made through the midbrains of seven(More)
We have demonstrated previously that many human cancer cell lines maintained in tissue culture possess specific cell surface receptors for human prolactin (HPRL) and human growth hor mone (HGH). In the present studies, the biological response in vitro of one human breast cancer cell line, T-47D, to the two pituitary hormones was examined. T-47D cells, when(More)
New cell production in the corpus callosum and subependyma of 4 month old mice was analysed by light microscopic radioautography after 3H-thymidine injections. In the subependymal region of the lateral ventricle, about 10% of cells were labeled in mice examined 2 h after 3H-thymidine, and 40 to 50% of cells were labeled after 7 d of isotope infusion. In(More)
The inferior colliculus in the rat midbrain is an auditory relay center whose functional maturation occurs postnatally. We examined by morphometry the vascularity and the nuclear profile density of the inferior colliculus in normal young rats at different ages (before and after the onset of auditory input). We also compared this region with a frontal region(More)
Rat placental lactogen-I (rPL-I), the first prolactin-like hormone expressed in the placenta during pregnancy in the rat, is known to influence maternal functions. In the present study, we have investigated the effects of rPL-I on the growth and development of cultured whole rat embryos. Rat embryos, with or without ectoplacental cone (EPC) attached, were(More)
The butyrylcholinesterase activity in the vasculature of the brain, choroid plexus, and pituitary, was studied histochemically in rats during postnatal days 1, 7, 14, 21 and 28. The brainstem auditory nuclei were used for comparison of vessels at different ages. We found intense butyrylcholinesterase activity in all intraparenchymal blood vessels,(More)
