WebJan 22, 2024 · Since small blood vessels in particular appear to increase in these mice and could indicate new blood vessel growth analogous to circumstances in which there is relative hypoxia or increased metabolic demand, we performed a qPCR assay to measure 84 genes related to hypoxia and angiogenesis (Fig. 3 A–G). WebCell proliferation was slightly increased (by 3-5%) by LR3-IGF1 (p<0.001). LR3-IGF1 had variable effects on progesterone production, whilst PPP reduced progesterone concentration (p<0.001) with or without LR3-IGF1 or IGF2 alone or in combination. IGF1 was detected in cell conditioned media and was increased by LH (50ng/ml) (p<0.001).
