Dissociation of the porcine anterior pituitary: the kinetics of luteinizing hormone release in response to luteinizing hormone-releasing hormone.
A method has been developed for disaggregating porcine anterior pituitary tissue and for providing dissociated preparations which have good, stable viability in culture. The secretory capacity for these preparations in terms of their ability to release luteinizing hormone in response to luteinizing hormone-releasing hormone has been documented in detail. In following the short-term kinetics of LH secretion a biphasic pattern of release has been demonstrated in which a sharp initial peak, maximal at 2 min, is followed by a second, more prolonged phase of release reaching a maximum between 10 and 20 min.
