About the Project

Voltage-sensitive calcium channels (VSCC) are ion channels found in the cell membrane that allow calcium (Ca2+) to enter the cell. These channels are an essential part of the cellular machinery allowing cells of excitable tissues to undergo action potentials and for synaptic transmission. VSCCs are also found in bone cells and predominantly in osteocytes, which make up 90% of bone cells. The osteocyte is believed to be the skeleton’s “mechanosensor” and is central to the regulation of bone density.

Osteocytes are embedded in the bone matrix in an interconnected network bathed in fluid whose flow is influenced by the body’s movement. Osteocytes respond to this fluid flow with an early response being an increase in cytosolic Ca2+. VSCCs are thought to be involved in the recovery of Ca2+ stores following mechanical stimulation. This research will investigate how VSCC function is affected by mechanical stimulation and how calcium channel blocker drugs affect their function and osteocyte metabolism. The student will be given training in in vitro cell culture, confocal microscopy and cellular electrophysiology.
