Human Growth Hormone Increases the Intracellular Free Calcium in Cultured Human Im-9 Lymphocytes

Abstract

We studied the effects of human GH (hGH) on intracellular free calcium concentration ([Ca2+]i) in cultured IM-9 lymphocytes an established human cell line possessing typical somatogenic receptors. [Ca2+]i was measured on cell suspensions by fluorescence spectrometry using the fluorescent probe fura-2. Resting [Ca2+]i levels were 93 ± 15 nM. After the… (More)
