Emerging human cell-based in vitro models for studying pituitary development and disorders.

Area of Science:

• Endocrinology and Developmental Biology
• Stem Cell Research
• Translational Medicine

Background:

• The pituitary gland is crucial for physiological homeostasis, regulating vital body functions through hormone secretion.
• Pituitary hormone dysregulation, caused by tumors or autoimmune diseases, leads to diverse symptoms.
• Species-specific differences in animal models limit human pituitary research, compounded by a lack of human cell lines.

Purpose of the Study:

• To review current in vitro experimental models for studying human pituitary gland development and function.
• To discuss the applications of these models in understanding pituitary physiology and related disorders.
• To highlight recent biotechnological advances in creating human pituitary cell models.

Main Methods:

• Utilizing long-term cultures of human pituitary tumor tissues.
• Generating pituitary hormone-producing cells from human pluripotent stem cells in vitro.
• Summarizing findings from established human pituitary cell models.

Main Results:

• Emerging in vitro models derived from human tissues and stem cells address limitations of traditional animal models.
• These platforms enable investigation of human-specific pituitary mechanisms.
• Advanced models facilitate deeper understanding of pituitary development, physiology, and disease.

Conclusions:

• Novel in vitro models, including stem cell-derived and tumor-derived cells, are revolutionizing pituitary research.
• These human-specific models are essential for studying pituitary development, hormone regulation, and diseases like tumors and autoimmune conditions.
• Further application of these models promises significant advancements in endocrinology and translational medicine.
