[DIfferentiation of enthesis and the synovial membrane in the rat].
The development of the knee joint in Wistar rats was observed from the 14th fetal day to the 40th postnatal day by light microscopy, transmission electron microscopy and scanning electron microscopy. The differentiation of the capsular ligamentous and tendinous attachments, synovial cavity, and A and B cells were particularly compared. Capsular attachments appeared for the first time at the 15th day of fetal life. The formation of the cavity started at the 17th day of fetal life. The differentiation of A and B cells was observed by the 20th fetal day by T.E.M., and only by the 15th postnatal day by S.E.M.
