What is the Most Common thing in all these
diseases???
  • Gene therapy is an experimental technique that
    uses Genes to treat or prevent disease.
  • The First Success Story of Gene Therapy
  • The first human to receive gene therapy treatment
    was a 4 year old girl with severe
    immune-deficiency disease.
  • This disease is caused by a faulty gene that
    fails to produce a vital enzyme.
  • In the therapy procedure, they extracted some of
    the girl's white blood cells.
  • Then, they exposed them to a genetically
    engineered virus that had lost its virulence but
    still carried normal versions of the gene that
    was not functioning correctly in the girl.
  • The virus invaded the white blood cells, and then
    these cells were transfused back into the girl.
  • Once back inside the girl's bloodstream, the
    cells began producing the proper enzyme.
  • Although the girl still needs follow-up
    treatments, she now leads a relatively normal
    life following the gene therapy.
  • This is one of the success stories of gene
    therapy.
  • In this to treat a disorder a gene is inserted
    into a patient's cells instead of using drugs or
    surgery.
  • The first attempt at modifying human DNA was
    performed in 1980 by Martin Cline
  • But the first successful nuclear gene transfer in
    humans was approved by the National Institutes of
    Health, was performed in May 1989.

Gene Therapy
  • The first therapeutic use of gene transfer as
    well as the first direct insertion of human DNA
    into the nuclear genome was performed by French
    Anderson in a trial starting in September 1990.
  • Between 1989 and February 2016, over 2,300
    clinical trials were conducted, with more than
    half of them in phase I

Confusion Between Totipotent vs. Pluripotent vs.
Multipotent?
What are the different types of stem cells?
What are the Stem Cells Throughout the Human
Lifecycle
What is Stem Cell?
What is Stem Cell Therapy?
What is the Most Common thing in all these
diseases???
  • Embryonic Stem Cells (ESCs) This is the only
    controversial stem cell type. ESCs are derived
    from blastocysts, a stage in the developing
    embryo. They can become any cell type within the
    human body.
  • Perinatal Stem Cells These cells are obtained
    during the period immediately before and after
    birth. Collection of these cell types does not
    impact the development of the fetus or newborn,
    so they are non-controversial.
  • Adult Stem Cells These are non-controversial
    cells found in living adults. Everyone has stem
    cells present in their bone marrow, fat (adipose
    tissue), and many other sites.
  • Induced Pluripotent Stem Cells (iPS Cells) iPS
    cells were discovered in 2006. They are
    non-controversial because they are adult cells
    that are genetically reprogrammed in a lab. Like
    embryonic stem cells, they can become any cell
    within the body.
  • Cancer Stem Cells (CSCs) Cancer stem cells are
    a type of stem cell that biotech and pharma
    companies are exploring because they play a role
    in facilitating the formation of tumors.
    Companies exploring CSCs are interested to
    discover how to manage and prevent cancer.
  • Embryonic stem cells Stem cells derived from
    embryos (controversial).
  • Pre-natal stem cells Stem cells derived from
    the fetus or supporting structures
    (non-controversial).
  • Post-natal stem cells Stem cells derived from a
    recent newborn (non-controversial).
  • Adult stem cells Stem cells derived from living
    humans (non-controversial). Common adult stem
    cell types include mesenchymal stem cells (MSCs),
    hematopoietic stem cells (HSCs), and neural stem
    cells (NSCs), among others.
  • Totipotent stem cells Cells that have the
    capacity to form an entire organism.
  • Pluripotent stem cells Can give rise to most,
    but not all, tissues within an organism.
  • Multipotent stem cells Undifferentiated cells
    that are limited to giving rise to specific
    populations of cells.

Stem Cell therapy
Ans Stem-cell therapy is the use of stem cells
to treat or prevent a disease or condition.
Ans Stem cells are cells with the potential to
develop into many different types of cells in the
body. They are part of the repair system for the
body.

Why do scientists want to use stem cell lines?
  • The reason scientists want to use stem cells is
    twofold
  • They hope to grow these stem cells into tissues,
    afflicted by certain diseases, to better assess
    what causes these diseases and how to create
    effective treatments and
  • scientists can use stem cells to repair or patch
    damaged cells in people with various diseases.

10
How Are Stem Cells Being Used in Medicine?
  • Today, most clinics that offer stem cell
    treatments administer Mesenchymal stem cells
    (MSCs), which they source from fat tissue or bone
    marrow.
  • Mesenchymal stem cells are a type of multipotent
    stem cell that is being explored for use in the
    orthopedic repair, pain management, arthritis,
    asthma, and many other applications.
  • MSCs tend to exert effects on other cells and
    tissues within the human body, which is called
    paracrine signaling.
  • Another stem cell type that is commonly used is
    the hematopoietic stem cell (HSC). HSC
    transplantation has been used for decades as a
    means of rebuilding the immune system after a
    patient undergoes radiation or chemotherapy.

11
  • Success Stories of Stem Cell Therapy
  • Blindness
  • On July 12, 2011, scientists injected retinal
    cells, derived from embryonic stem cells, into
    the eyes of two patients suffering from
    progressive blindness. The patients who received
    the therapy currently exhibit no signs of adverse
    effects from the treatment and are reporting
    small improvements in their vision. The
    transplanted retinal pigment cells have
    integrated into the eye tissue and are aiding
    photoreceptor cells to function again.
  • Parkinsons Disease
  • Scientists are currently treating some patients
    with Parkinsons disease with stem cell therapy.
    So far, the two patients treated to date are
    showing no ill effects from the therapy, which is
    being studied in a phase 1 trial involving 12
    Parkinsons disease sufferers conducted by
    researchers at the Royal Melbourne Hospital in
    Australia.
  • Spinal-Cord Injury
  • In the June 2017 issue of Forbes magazine, they
    disclose a couple of the current findings in the
    field of stem cell science and medicine. As part
    of a 2016 trial, neurologist Charles Liu, infused
    ten million stem cells into a paralyzed patients
    spinal cord. Within months, the patient could
    lift weights, write his name and feed himself.
    Although Lius study is not complete, and the
    treatment is not standard therapy, researchers
    were encouraged enough by the results to extend
    the treatment to people with less-severe spinal
    injuries who would have been too risky to include
    in initial tests.

1.1 Some Basics
What is the difference between Nucleotides, Gene,
chromosome, Genome Protein?
  • Our Human Body having 11 Systems
  • From smallest to largest Nucleotide, Gene,
    Chromosome, Genome.
  • Nucleotides are the smallest building blocks of
    DNA. There are four nucleotides (A, G, T, C)
    which arrange in pairs to form the long double
    strands typical of DNA molecules.
  • A Gene is a segment of DNA which codes for the
    amino acid sequence of a particular protein. A
    gene is therefore composed of many pairs of
    nucleotides. Eg. APOE e4 Gene appears to increase
    the risk of Alzheimer Disease.
