Bezos is also willing to cannibalize his own companies: Amazon spent nearly $1 billion to acquire shoe retailer Zappos in 2009, but its Amazon shoe site competes directly with Zappos. As well, Bezos is adept both at changing the subject to one of his choosing and at crafting a reality that suits his purposes.
Fibroblasts produce three types of connective tissue fibers: collagenous fibers, elastic fibers, and reticular fibers. Of these, collagenous and elastic fibers are the most abundant. Fibroblasts produce three types of connective tissue fibers: collagenous fibers, elastic fibers, and reticular fibers.
Fibroblasts are by far the most common native cell type of connective tissue. The fibroblast synthesizes the collagen and ground substance of the extracellular matrix. These cells make a large amount of protein that they secrete to build the connective tissue layer. Some fibroblasts have a contractile function; these are called myofibroblasts. Chondrocytes and osteocytes form the extracellular matrix of cartilage and bone. More details and chondrocytes can be found later in this laboratory; osteocytes will be covered in the Laboratory on Bone. The macrophage is the connective tissue representative of the reticuloendothelial, or mononuclear phagocyte, system.
