WHAT IS BONE MADE OF? The hard matrix of bone is made of crystals of calcium phosphate and other minerals, and fibers of protein called collagen. The minerals make bone hard, while the collagen fibers are arranged lengthwise to make bone flexible. Both are produced by cells called osteocytes, found throughout the matrix.
