EP24.15 as a Potential Regulator of Kisspeptin Within the Neuroendocrine Hypothalamus.

abstract：:It has previously only been possible to assess osteoclastic bone resorption in intact bone, where other cell types may modify or mediate osteoclastic responses to environmental agents. We have recently developed techniques which enable us to measure bone resorption by osteoclasts extracted from bone and have used thes...
