Composition of human periodontal ligament cells in tissue culture. 1981

L Blomlöf, and P Otteskog

The cells in the PDL of monkeys have been demonstrated to have an unusual growth behavior in vitro since fibroblast-like cells have been reported to grow on top of epithelial-like cells. In this study growth of epithelial-like cells along with fibroblast-like cells was seen in human PDL from three out of 15 permanent teeth when explantation technique was used whereas only fibroblast-like cells were seen after enzymatical degradation. Occasionally fibroblast-like cells were seen growing on top of epithelial-like cells.

D002648	Child	A person 6 to 12 years of age. An individual 2 to 5 years old is CHILD, PRESCHOOL.	Children
D004847	Epithelial Cells	Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.
