Title: Types of Stem Cells
1(No Transcript)
2What are stem cells?
- Stem cells are unspecialized cells of the human
body. - They can transform and/or multiply into
specialized cells. - Through a laboratory procedure known as
differentiation stem cells procured from one part
of the body can become/grow into other kinds of
cells. - They work to repair the body by generating
healthy cells that can replace the cells damaged
by disease.
3The Four Types of Stem Cells
- Embryonic Stem Cells (ESCs)
- Adult Stem Cells (ASCs)
- Induced Pluripotent Stem Cells (iPSCs)
- Mesenchymal Stem Cells (MSCs)
4Embryonic Stem Cells (ESCs)
- Derived from unused embryos that are from an IVF
procedure - Derived from the inner cell mass of an embryo in
its early stages of development - Typically grown in laboratory conditions
- Have self-renewing potential
- Can differentiate into clinically relevant cell
types like dopamine neurons, cardiomyocytes, beta
cells, etc - Do not have any specific characteristics like
shape, or gene expression pattern
5Ban on ECS in 2001
Former US President George W. Bush put a ban on
the funding of research on stem cells derived
from human embryos because it involved the
destruction of human life.
6Adult Stem Cells (ASCs)
- Undifferentiated cells Procured from fully
developed tissues like the brain, bone marrow,
etc - Multipotent cells (limited ability to
differentiate into other types of cells) - Essential for maintaining the integrity of the
tissue in which they are found - May be used for tissue repair and regenerative
medicine, like stem cell therapy
7Induced Pluripotent Stem Cells (iPSCs)
- First developed by Japanese physician and
researcher Shinya Yamanaka in 2006 - Derived from blood cells
- Genetically reprogrammed to exhibit the
characteristics of embryonic stem cells - Generated by introducing specific types of genes
into adult cells - Can self-renew and also differentiate into any
cell type in the body - Reduced risk of immune rejection (iPSCs are
sourced from the patients own cells
8Mesenchymal Stem Cells (MSCs)
- First found in the bone marrow
- Capable of making bone, cartilage, and even fat
cells - Similar to adult stem cells
- Possess anti-inflammatory, immunomodulatory,
self-renewal, cell-division, signaling, and
differentiation properties - Can divide and develop into many specialized cell
types in specific organs and/or tissues - Can become unique stem cell types and create more
stem cells when cultured in a lab - Can replace cells that are diseased or damaged
Mesenchymal stem cell transplantation can help
slow down the rate of degeneration caused by MND,
Parkinsons and other illnesses.
9Source of MSCs
- Umbilical cord
- Bone marrow
- Adipose tissue
- Peripheral blood
- Placental tissue
- Synovial fluid (present in joints)
- Dental pulp
- MSCs may also be derived from endometrial polyps
and menses blood.
10Differentiation properties of MSCs
- MSCs can differentiate into a variety of cell
types like - - Osteoblasts (bone cells)
- Adipocytes (fat cells)
- Chondrocytes (cartilage cells)
- Research suggests MSCs can also differentiate
into - - Epithelial cells (found inner and outer surfaces
of your body) - Endothelial cells (found in blood vessels)
- Neurocytes (nerve cells)
- Myocytes (muscle cells)
- Cardiomyocytes (heart muscle cells)
- Hepatocyte (liver cells)
- Pancreatic cells
11The classification of stem cells
- Totipotent
- The first few cells that appear when a zygote
starts to divide - Can differentiate into all possible cell types
- Also called omnipotent stem cells
- Self-renewable
- Pluripotent
- The cells from an early embryo
- Can differentiate into almost any cell type
- Self-renewable
- Multipotent
- Can differentiate into a closely related family
of cells - Self-renewable
12The classification of stem cells
- Oligopotent
- Adult lymphoid and myeloid stem cells
- Can differentiate into a few different types of
cells - Self-renewable
- Unipotent
- Can only produce their own type of cells
- Self-renewable
13Types of stem cell therapy
Autologous therapy ? Cells are procured from
patients own bone marrow, blood, or fat
tissue Allogeneic therapy ? Cells are procured
from external donors
14Administering stem cells
- Stem cells can be administered in the following
ways - Intravenous
- Intrathecal (directly into the spinal canal)
- Inject into problem areas like hips, hands,
knees, etc.
