For example, follicle cells
can secrete maturation-inducing substances that presumably use the junctions between follicle cells
and oocytes to promote GVBD and ovulation (Schroeder, 1981; Beers and Olsiewski, 1985; Sato and Koide, 1987; Cerada et al.
Our immunochemical results showed that the follicle cells
were stained with strongly positive PR for each ovarian stage in female E.
Because the oocytes apices were free even in the ovary studied in October, the flat cells maybe abnormal vestiges of follicle cells
After physical expulsion from the ovary, the egg and accompanying follicle cells
are captured by a fallopian tube.
This localized signal from the oocyte to the follicle cells
normally leads to dorsal follicle cell
delimitation and orientation of the future dorsoventral axis of the embryo.
The follicle cells
have vacuoles in their cytoplasm that are observed both under LM and EM (Fig.
It is generally considered that the binding of TGF-beta 1 receptors induces apoptosis of hair follicle cells
and triggers hair loss.
A transgenic mouse was created that is hairier than other mice, and mice follicle cells
were persuaded to grow hair after they were implanted in another animal, suggesting that a baldness cure might be possible.
Lavker and Sun plan to continue studying hair follicle cells
, in part to explain why laboratory-induced skin tumors in mice usually seem to originate in the upper follicle but not the bulge itself.
Scientists have successfully conducted an experiment in which follicle cells
transplanted from a man's scalp caused male hair to sprout from a woman's arm.
Cyoctol binds itself to the hair follicle cells
, preventing the cells from binding with dihydrotestosterone (DHT), a male hormone.
When applied to skin in a specific manner, Levulan(TM) appears to be taken up preferentially by the rapidly growing hair follicle cells
, and converted to protoporphyrin IX (PpIX), a potent photosensitizer.
5-HT-IR cells was observed around the follicle cells
(Figure 2A and B).
However, unlike mammalian oocytes that develop within follicles, nemertean oocytes characteristically lack a surrounding sheath of follicle cells
and often respond differently to maturation-related cues than do mammalian oocytes.
Histological analysis of Leptobotia elongata Bleeker ovaries revealed five stages in oocyte development (oogonia, previtellogenic oocytes, vitelline vacuolated oocytes, vitellogenic oocytes and mature oocytes) based on nucleoli, follicle cells
