Polyclonal antisera to synthetic peptides matching sequences on the cytoplasmic regions of
connexin-43, a gap junction protein first identified in rat heart, have been used to …

Gap junctions are channels connecting cells that function in cell‐to‐cell communication. Gap
junctions are abundant in osteoblastic cells. Membranes enriched for gap junction plaques …

The structure of gap junctions in osteoblast-like cells (OBs) and the connexins (cx) that build
up these structures were characterized by ultrastructural, immunocytochemical, and …

Intercellular gap junctions have been previously described at contact sites between surface
osteoblasts, between osteoblasts and underlying osteocytes, and between osteocyte cell …

Morphological evidence shows that osteocytes, bone cells that exist enclosed within bone
matrix, are connected to one another and to surface osteoblasts via gap junctions; however …

We examined i) the kinds of connexins, component proteins of gap junctions, that are
expressed in osteoblasts and ii) the relationship between the expression of gap junctions …

Cell membrane specializations occur at contact sites between adjacent osteoblasts and
osteoblasts and osteocytes. These junctions have been described by other investigators as …

The spatial and temporal expression of three closely related members of the connexin family
of gap junction proteins (connexin42, Cx42; connexin43, Cx43; and connexin45, Cx45) was …

The present study investigated the effects of elevated cytoplasmic free calcium
concentrations ([Ca 2+] i) on the permeability of gap junctions between cultured osteoblast …

The inaccessibility of osteocytes due to their embedment in the calcified bone matrix in vivo
has precluded direct demonstration that osteocytes use gap junctions as a means of …
