概括
牛头组织需要特定的培养基来进行持续的体外研究. 表皮细胞对于在尾部再吸收过程中甲状腺激素诱导的介质细胞回归至关重要.
科学领域:
- 两动物发育生物学
- 在体外组织培养技术.
- 变形的内分泌学.
背景情况:
- 以前用于尾的体外培养方法在Rana pipiens中取得了成功,但在Rana catesbeiana中没有成功.
- 在没有激素刺激的情况下,牛头组织在体外表现出自发的回归,需要优化培养条件.
研究的目的:
- 开发一种改进的体外培养基,用于牛头组织.
- 研究甲状腺激素诱导的尾部回归过程中表皮和介质细胞之间的相互作用.
- 阐明表皮细胞在介质细胞回归中的作用.
主要方法:
- 对各种介质的查,以确定牛幼组织培养的最佳条件.
- 使用RPMI-1640介质补充胰岛素和转激素,以成功维护组织.
- 采用外科和化学方法来隔离或去除表皮层.
- 准备"皮肤调节介质" (SCM) 来评估表皮影响.
主要成果:
- RPMI-1640与胰岛素和转激素支持公牛青的组织培养.
- 经过手术准备的介质细胞只能与甲状腺激素回归,如果表皮细胞存在.
- 化学剥离的介质细胞 ("裸尾") 对甲状腺激素没有反应.
- 裸尾在含甲状腺激素的SCM中回归,表明表皮信号传递.
结论:
- 优化的培养基对于在体外研究两变形至关重要.
- 表皮细胞在调解尾部介质细胞回归方面发挥着关键的,依赖激素的作用.
- 这项研究表明,在子尾部再吸收过程中,介质细胞回归的表皮依赖性.

Synthesis and Regulation of Thyroid Hormones
4.8K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Functions of Thyroid Hormones
2.9K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
