Platelet-Derived Growth Factor, known succinctly as PDGF, is a cornerstone in the biology of tissue repair. From the moment of vascular injury, PDGF is released by platelets and other cells to orchestrate a cascade of events that guide cells to the wound site, stimulate their proliferation, and recruit the essential support systems for regeneration. This…

Heat is a universal traveller. It moves from regions of higher temperature to regions of lower temperature, carrying energy with it. To describe this movement precisely, engineers and scientists rely on a fundamental concept known as the heat flux definition. In its simplest form, heat flux quantifies how much thermal energy crosses a given surface…
