Detection of a kallikrein in the mouse lactating mammary gland: a possible processing enzyme for the epidermal growth factor precursor.

abstract：:Japanese quail, a species with a precocial pattern of development, were used as a model for studying the ontogeny of thyroid responses to TSH. Thiourea was administered to embryos early in incubation, and the effects were assessed by measuring thyroid 32P uptake, serum thyroid hormones, thyroid weights, and body weigh...
