Iii a previous work wc dernonstrated that germ and epitheiial celis of the atrophic right ovary and of the medulla iii the icft functioning ovary uridergo regression while interstitial celis are preserved. The objective of the prosent study was tu analyze the relationship belween nerve fibers and nerve cnciings aoci interstitial cciis from both ovaries ouring crnbryogenesis in [he chick. To this purpose, lcft and right ovaries from crnbryos of 7 to 19 days of dcvelopment \\'Cre processed for uitrastructira1 study and ultracytochernical determination of cid phosphatasc. At 7 days. isolated interstitial célis were found in the cent ral region O!: hoth ovaries, containin SER, Goigi apparatus, mitochondria wth tubular cristae and abundant lipidic vacuoles. Ncrvc fibers and nerve odings were scarce. From the lltday, interstitial ccils vcie founc1 grouped in the right ovary aoci jo the medulia of the !cft one, and were related lo nerve bundies surroundcd by Schwann celis. The nerve encling, jo cjose contact with the membrane of interstitial celis, container! mifochon- dna, microtubulcs aoci sma]i ami big 'esicles, sorne with ari eiectrodensc con- tent. This reiationship betwecn inters titial celis and nerve endings and fibers was more frequent from the 15th day. The activitv of acid p1iosphatase locali-
zed in gerrn and cpitheiial cells pre- cnteci a rnorc' intense rcaction jo the right ovary and in the niedulia of thc' Jeft ovary at 15 days. Enzyrne activity was not detected in int.erstitini celis nor íri nerve endings and fibers al: the cliffc- runt agcs studied. Thesc results suggest that nerve fibers and nerve endings vouid ix' necessary for interstitial celis dil[ercntiation in both ovaries of the chick crnbryo.
