About this course
Cells get older and die. It is a process that takes place, sometimes over days, sometimes over years.
In this course, I will cover how cells grow, mature, and then age and become senescent. I use the examples of neurons (dementia and ALS) and skin cells (aging skin) to illustrate the two ways that cells age.

Cells that age have to have mature proteins.
These are the proteins that live in specialized cells. It is a benefit to become specialized. This is the way our cells can produce insulin or thyroid hormones or antibodies that fight infections.
Unfortunately, it is also how cells age.
In this module, I will walk you through typical mature proteins and their defining characteristics. In future modules, I will discuss how cells age.
The goal for this course is to see a cell going from an immature baby-like state, to a mature adult state, to an elderly state.
There are reasons that cells age: They accumulate a particular type of protein: a mature protein.
Immature cells - like stem cells - can undergo planned cell death.
This article demonstrates a table of R1 and R2 proteins and the following attributes to these proteins:
Lessons will be added as they are completed. Two lessons will be added each week.
