Periodontal ligament fibroblasts can generate a force for tooth Eruption as:

Periodontal ligament fibroblasts are ectomesenchymal in origin whereas gingival fibroblasts are mesodermal in origin. Expression of alkaline phosphatase and cyclic AMP is more in periodontal ligament fibroblasts. Gingival fibroblasts are less proliferative Periodontal ligament fibroblasts can generate a force for tooth eruption as they are motile and contractile. Fibroblasts in PDL are capable of collagen degradation also.
