Study Notes

Stem Cells

Stem cells are undifferentiated cells that have the ability to develop into various specialized cell types.
They play crucial roles in growth, repair, and development processes.
Stem cells are a vital component of multicellular organisms
Stem cells can be categorized into different types like embryonic stem cells, adult stem cells, and induced pluripotent stem cells.

Types of Stem Cells

Embryonic stem cells: Derived from embryos, these cells are capable of differentiating into any cell type in the body.
Adult stem cells: Found in various tissues, these cells are specialized to generate cells within that particular tissue.
- Limited ability to become other cell types.
- Limited ability to divide and multiply.
Induced pluripotent stem cells (iPSCs): Created by reprogramming adult cells to acquire a similar capacity to embryonic stem cells.
- Good potential in medicine but a relatively new area of research.

Medical Uses

Embryonic stem cells: Used in experimental treatments to regenerate or repair damaged tissues and organs.
Adult stem cells: Used in therapies like stem cell transplants.
iPSCs: Used to model various diseases in investigations which could lead to potential new treatments or therapies.
- Used in modelling diseases like Alzheimer's disease, heart diseases, kidney disease, muscle disorders, diabetes alongside others.

Specialized Cells

Multicellular organisms are composed of specialized cells with diverse functions.
Different cell types within an organism have distinct roles.

Starter Questions

Discussion prompts for a video related to stem cells:
- How many members were in the video?
- What special job roles were observed?
- Were all job roles similar?
- What was the goal of the emergency team depicted in the video.
Follow up question on relation to human organization: How does the emergency team relate to the organization of multicellular organisms (humans)?

Defining Stem Cells

A stem cell is an undifferentiated cell within an organism with the ability to repeatedly divide.
These undifferentiated cells are capable of generating new cells from different cell types through differentiation.
