Differentiation in the young chick blastoderm is affected by thymidine at concentrations higher than 8.2 x 10(-4) M. Blastoderms at the hypoblastic island stage cultured continuously in the presence of thymidine form an atypical primitive streak which is not capable of inducing the embryonic axis. However, blastoderms with a mature streak escape the effect of thymidine and develop normally.
在幼雏胚盘的分化受到浓度高于8.2×10⁻⁴ M的胸苷的影响。在胸苷存在的情况下持续培养的下胚层岛阶段的胚盘形成一条非典型的原条,其不能诱导胚胎轴。然而,具有成熟原条的胚盘可避免胸苷的影响并正常发育。
