A cDNA clone THE 3 (tobacco heart embryo 3) was isolated by differential screening from tobacco (Nicotiana tabacum L.) heart embryo cDNA library as compared with the globular embryo cDNA library. The distribution of THE 3 mRNA in tobacco heart embryos and globular embryos was investigated by a whole_mount in situ hybridization technique, showing that THE 3 is preferentially expressed in heart embryos.展开更多
目的 探讨大鼠消化道是否存在 Gn RH受体 m RNA及其定位。 方法 用原位杂交组织化学法。 结果 胃底腺壁细胞、胃小凹上皮细胞可检测到较强的 Gn RH受体 m RNA杂交信号。3段小肠绒毛上皮细胞、小肠腺细胞可检测到较强的 Gn RH受体 m...目的 探讨大鼠消化道是否存在 Gn RH受体 m RNA及其定位。 方法 用原位杂交组织化学法。 结果 胃底腺壁细胞、胃小凹上皮细胞可检测到较强的 Gn RH受体 m RNA杂交信号。3段小肠绒毛上皮细胞、小肠腺细胞可检测到较强的 Gn RH受体 m RNA杂交信号。盲肠、结肠和直肠的粘膜上皮细胞、肠腺上皮细胞也能检测到 Gn RH受体 m RNA杂交信号。信号物质均分布在胞质内 ,胞核呈阴性。 结论 大鼠消化道能合成 Gn RH受体。Gn RH也是一种胃肠激素 ,它由消化系统自身合成 。展开更多
