Study Notes
Lecture 1: Introduction to Signalling in Multicellularity
- Primary focus: Introducing the concept of signalling in multicellularity and its importance
Signalling in Multicellularity
- Function: Enables cells to communicate and coordinate their behaviour to form and maintain a multicellular organism
Cells in Multicellular Organisms
- Described as: Social entities that communicate with each other to achieve common goals
Signalling in Biology
- Compared to: A wireless communication network, where cells are the devices and signals are the transmitted information
Lecture 2: Signalling Series
- Topic: Intercellular signalling mechanisms and their role in development and homeostasis
