Osteonecrosis of the jaw fatty degeneration and/or necrosis, often with pooled fat from destroyed adipose cells (oil cysts) and with marrow fibrosis (reticular fatty degeneration)"" are seen. These changes are present even if ""most bony trabeculae appear at first glance viable, mature and otherwise normal, but closer inspection demonstrates focal loss of osteocytes and variable micro cracking (splitting along natural cleavage planes). The microscopic features are similar to those of ischaemic or aseptic osteonecrosis of long bones, corticosteroid-induced osteonecrosis, and the osteomyelitis of caisson (deep-sea diver's) disease"". In the cancellous portion of femoral head it is not uncommon to find trabeculae with apparently intact
Dental pulp stem cells growth, differentiation, and angiogenic potential of HDPCs. Results suggest that these metaphosphates may be candidates for dental pulp tissue engineering and regenerative endodontics. Dental pulp is the soft living tissue inside a tooth. Stem cells are found inside the soft living tissue. Scientists have identified the mesenchymal type of stem cell inside dental pulp. This particular type of stem cell has the future potential to differentiate into a variety of other cell types including: Dental pulp stem cells Dental pulp stem cells (DPSCs) are stem cells present in the dental pulp, the soft living tissue within teeth. They are multipotent,
