Such conflicting results could be due to species-specific differences or to variations in experimental procedures such as the type of maturation inducer that is used and whether or not oocytes are associated with follicle cells
(Homa, 1995; Fan et al., 2004).
A single layer of follicle cells
surrounded the oocytes.
Ascidian eggs block polyspermy by two independent mechanisms, one at the egg plasma membrane, the other involving the follicle cells
Retraction of the follicle cells
, which exposes the egg jelly coat in T.
Thus, follicle cells
can stimulate or inhibit maturation, and such regulatory signals may be transported through the junctions at the follicle cell-oocyte interface.
measured 8-10 [micro]m in thickness.
Naturally, hair follicles surrounded by subcutaneous adipose cells and by dermis form an interfollicular dermal macroenvironment, which is important in maintaining the proper growth of bulge and follicle cells
[11, 61, 62].

and inhibits the alkaline phosphatase activity and the expression of DLX3," Tissue & Cell, vol.
Legends: Primary oocytes (PO), primordial follicle cells
(PFH), zona pellucida (ZP), theca interna (TI), theca eksterna (TE), antrum (A), granuloza cells (GH), Secondary oocytes (PO), corona radiata (CR), cumulus oophorus (CO), Medulla (M).
In addition, a number of healthy tissues (such as blood cells, follicle cells
of hair and many of cells in digestive system) have quick growth and proliferation in comparison with other tissues.
Analysis of the HSP70:GAL4 effect in the ovary is likely to provide new insights into the normal function of ovarian follicle cells
. We have designed a genetic screen to identify novel mutants that rescue the defect in egg development after HSP70:GAL4 expression.
(74) Early studies showed that oocyte growth and development are strictly dependent on the supply of nutrients from the follicle cells
. Later studies demonstrated that the meiotic maturation of oocytes is subject to regulation by the somatic compartment of the ovarian follicle.
