The good news, he said, is that the majority of damaged hard drives can be recoveredâalbeit for a hefty price. DriveSavers charges an average of $1,000 to $1,500 to save the data from a single, consumer-grade drive, though the company is offering $500 off for severe weather victims.
Stem cells are remarkable cells that can transform into virtually any other cell type found in the body. Itâs hoped that developing new ways to cultivate stem cells into bone tissue could remove the need for hip replacements and complicated bone grafts.
Pathway: Platelet degranulation. Platelets function as exocytotic cells, secreting a plethora of effector molecules at sites of vascular injury. Platelets contain a number of distinguishable storage granules including alpha granules, dense granules and lysosomes. On activation platelets release a variety of proteins, largely from storage granules but also as the result of apparent cell lysis. These act in an autocrine or paracrine fashion to modulate cell signaling. Alpha granules contain mainly polypeptides such as fibrinogen, von Willebrand factor, growth factors and protease inhibitors that that supplement thrombin generation at the site of injury.
