An in vitro model has been developed to study migration, survival, proliferation, and capillary-like differentiation of human microvascular endothelial cells (HMVECs) in an environment that avoids tumor promoters and complex matrices. HMVEC monolayers were plated, then induced to form three-dimensional, capillary-like networks by overlaying with human type(More)
The onset of metabolic acidosis causes an increased transcription of the renal phosphoenolpyruvate carboxykinase (PCK) gene. When transgenic mice carrying a bovine growth hormone (bGH) gene driven by the -460 to +73 segment of the PCK promoter were made chronically acidotic, the bGH mRNA was increased twofold after 4 days. Confluent and well-differentiated(More)
We recently showed that normal fibroblasts mediate capillary-like differentiation of human microvascular endothelial cells (HMVEC) in a 3-D angiogenesis model. Here, we show that a collaborative effect of VEGF-A and alphaVbeta3 integrin is critical in fibroblast-mediated angiogenesis because enhancement of both VEGF production by fibroblasts and beta3(More)
