Welcome to 'Introduction to Developmental Biology' course ! • Cells talk! This lecture explores the intricate language of cell-cell signaling pathways, the molecular conversations that orchestrate the symphony of development. We'll revisit the receptor tyrosine kinase (RTK) pathway, focusing on how RAS GTPases fine-tune these critical signals. Next, we'll unravel the JAK-STAT pathway, where STAT proteins act as express messengers, directly relaying instructions from the cell surface to the heart of the nucleus. Get ready for a deep dive into the Hedgehog pathway, famed for its role in shaping tissue boundaries, guiding limb development, and steering neural differentiation. Its secret weapon? A cholesterol-modified signal that sets it apart from the crowd! Finally, we'll explore the multifaceted world of Wnt signaling, a key player in muscle development, brain patterning, stem cell fate, and even sex determination. With three distinct modes of action – canonical, planar cell polarity, and Wnt/calcium pathways – Wnt orchestrates a dazzling array of developmental events. • NPTEL Courses permit certifications that can be used for Course Credits in Indian Universities as per the UGC and AICTE notifications. • To understand various certification options for this course, please visit https://nptel.ac.in/courses/102106084 • #cellsignaling #RTK #JAKSTAT #Hedgehog #Wnt #pathways #signaltransduction
