What 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.

3
The Four Types of Stem Cells
  • Embryonic Stem Cells (ESCs)
  • Adult Stem Cells (ASCs)
  • Induced Pluripotent Stem Cells (iPSCs)
  • Mesenchymal Stem Cells (MSCs)

4
Embryonic 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

5
Ban 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.
6
Adult 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

7
Induced 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

8
Mesenchymal 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.
9
Source 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.

10
Differentiation 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

11
The 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

12
The 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

13
Types 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
14
Administering 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.

15
Stem cell therapy at Indias first ISO-Certified
Stem Cell Research Center
  • Plexus Neuro and Stem Cell Research Centre uses
    autologous mesenchymal stem cells.
  • The procedure is conducted by Dr. Sadiq, Indias
    no. 1 stem cell specialist, and his team of
    highly-skilled and experienced stem cell
    specialists.
