  1. 01AnimalAnimal study (in vivo)Efficacy outcome

    In rabbit cartilage defects, hPTH(1-84) prevented observed chondrogenic differentiation throughout the experimental period versus saline.

    Summary
    In contrast, no evidence of chondrogenic differentiation was seen at any time during the experimental period in the defects treated with PTH.

    Recombinant human PTH(1-84) (hPTH[1-84]) (25 ng/h) then was administered into the joint cavity with an osmotic pump, or in control animals, saline alone was administered.
  2. 02AnimalAnimal study (in vivo)Mechanism

    In rabbit cartilage defects, PTH did not interfere with reparative cell proliferation.

    Summary
    Application of PTH did not interfere with proliferation but inhibited chondrogenic differentiation of the cells resulting in the formation of fibrous tissue that lost the expression of PTH/PTHrP receptor within 4 weeks.
