Eggs were isolated from ovaries and oviducts of the golden hamster and the components of zonae pellucidae were examined using density gradient SDS-polyacrylamide electrophoresis. Zonae of ovarian eggs (ZP-OVA) had three major components corresponding to the so-called ZP-1, ZP-2, and ZP-3. Zonae of recently ovulated eggs collected from oviducts (ZP-OVI) had(More)
Normal human cells have a replicative life span and therefore senesce. Usually, normal human cell strains are differentiated cells and reach a terminally differentiated state after a number of cell divisions. At present, definitive differences are not known between replicative senescence and terminal differentiation. TIG-1 is a human fibroblast strain(More)
A monoclonal antibody (mAb) designated AZPO-8 was produced by hybridizing a mouse myeloma with spleen cells from BALB/c mice immunized with materials obtained from the hamster oviduct. With an immunofluorescence test, AZPO-8 reacted with the zona pellucida (ZP) of ovulated eggs in the oviduct (ZP-OVI) but not with the zona pellucida of eggs in the ovary(More)
A glycoprotein designated ZP-0 is secreted from the epithelial cells of the oviduct and is bound to the zonae pellucidae (ZPe) of the oviductal eggs. We have previously established a monoclonal antibody reacting with ZP-0, termed AZPO-8. In the present study, we have examined the effect of AZPO-8 on in vitro fertilization in the hamster. Treatment of the(More)
Nerve growth factor (NGF) plays a critical role in the trigeminal ganglion (TG) following peripheral nerve damage in the oral region. Although neurons in the TG are surrounded by satellite glial cells (SGCs) that passively support neural function, little is known regarding NGF expression and its interactions with TG neurons and SGCs. This study was(More)
