you want to continue the conversation,
there are two excellent ways to do that:

Starts Sept 1st Tuesday and Thursdays 2-3:20 CCIS L1-140
Special 6 pm sessions in eHub, Hub Mall 9007 on Sept 3rd,
8th, and 10th http://www.singularitycourse.com

3. Stem Cell Technologies on Google
Trends – News Headlines and Forecast

4. Current transplant protocols reach
fewer than 10% of those in need.

5. Worldwide 1.2 million people are in
need of transplantation for end
stage organ failure. Current
transplant protocols reach fewer
than 10% of this number.
Regenerative medicine can save the
remaining 90%, over one million
people annuallly!

6.  For the first time, a patient has received a
synthetic windpipe (trachea) that was created in a
lab with the patient's own stem cells.
Regenerative Medicine Already Here!
Working for Tubular Organs, Bladder,
Trachea, Esophagus, Vagina.

7.  ViaCyte Announces Highly
Anticipated Encapsulation Clinical
Trial Site Expansion into Canada
 JDRF-funded researcher, Dr. James Shapiro
will be the lead investigator at the Canadian
site. TORONTO, July 29, 2015 -- ViaCyte, Inc.
announced the opening of a second site in its
Phase 1/2 trial for Type I Diabetes which utilizes
PEC-01™ pancreatic progenitor cells and the
proprietary Encaptra® drug delivery system which
is designed to protect the transplanted cells from a
patient’s immune system.

12. The Positive Aspects of Stem Cell Therapies,
The True Hope, Has Potential to Reverse Three
Looming Problems in Medicine:
1. The loss of “luster” in transplantation.
2. Workforce problems in nephrology due to lack of appeal
to young people/potential trainees worldwide.
3. Technological unemployment in medicine due to

13. “They will never be able to reverse those
trends.” Together we can do those things,
reverse those trends, make life good again!

29. The Technological
Singularity

30. Podocytes go wandering into the
interstitium! Song et al.

31. Many problems with stem cell generate
organs not being discussed. Do not exclude
yourself from the action in this area!

32. Many problems with stem cell generate
organs not being discussed. Need to get
those conversations to happen.
 The recellularized organ clots like crazy, impossible to
regenerate more than 80% of endothelial surface. Artificial
heparized surface not fenestrated. Cell traffic abnormal.
 Hard to get right types of cells to right places.
 Podocytes seems to be terminally differentiated cells,
when attempt to culture them they turn into different type of
cell.
 Kidney progenitor stem cell difficult to identify, kidney work
has lagged behind.
 Easy to make stem cell generated kidneys that lack loop of
Henle. Could produce lethal polyuria. What is “function”?
 Many old fashioned questions of physiology about how the
stem cell generated organ works, not just true for kidney,
true for every organ.

33.  Transplant
pathologists will also
become tissue
engineering
pathologists,
pathologists who
analyse organs grown
from stem cells. This is
not something beyond
us, we can adapt to a
work life that includes
stem cells.. Someone
needs to cross the
disciplines,

34.  Many of the questions
that need to be posed
about stem cell
generated organs are old
fashioned questions,
intact nephron
hypothesis, cell
regeneration, stunned
myocardium, contraction
band necrosis etc. Use
your nostalgia! Stimulate
conversations between
stem cell researchers and
transplant physicians.

35. Beginning at the Very Beginning!
 “We are at the very beginning of time for the human race. It
is not unreasonable that we grapple with problems. But
there are tens of thousands of years in the future. Our
responsibility is to do what we can, learn what we can,
improve the solutions, and pass them on.” - Richard P.
Feynman, (1918-1988) Physicist, Nobel Prize Winner
 "The sense of the future is behind all good policies. Unless
we have it, we can give nothing either wise or decent to
the world." - Snow CP, (1905-1980) Novelist and
Philosopher.
 "To a large extent, the future lies before us like a vast
wilderness of unexplored reality. The God who created and
sustained the evolving universe through eons of progress
and development has not placed our generation at the tag
end of the creative process. God has placed us at a new
beginning. We are here for the future." - Sir John
Templeton (1912-2008 ), Financial Analyst

36. Beginning at the Very Beginning!
 Like 1851 when the first International Classification of
Diseases was presented in the Grand Exhibition of
Technology at London’s Crystal Palace
 Emphasis was on cause of death

37. Classification focus is on sustaining life.
 Native and transplanted organ diseases can also occur in
tissue engineered organs.
 The classification focus of the new pathology discipline of
Regenerative Medicine/Tissue Engineering Pathology is
exactly the opposite of traditional classification of disease
which starts with causes of death. In Regenerative
Medicine/Tissue Engineering Pathology the emphasis is on
the degree of normality necessary to sustain life:
 Normal,
 Abnormalities of unknown functional significance,
 Abnormalities which will impair the main functions of the
organ,
 Abnormalities leading to severe organ dysfunction where
function may not be great enough to sustain life.

38. Song et al. Interstitium, vessels, and glomeruli with missing cells.
Disordered tubule formation with multiple interconnecting
lumina of differing sizes. “Can you really call this a kidney?” (Yes!)

39. Song et al. In addition to missing cells and disordered structures,
you have cells in the wrong places. Podocytes in the interstitium.

40. Focus of Tissue Engineering Pathology
 The focus of tissue engineering pathology will shift to
the question: “Is this organ structurally intact enough to
function safely and adequately in the recipient?” Using
the kidney as an example, the specific questions
become: (Images by Korey Fung)
 1. Are there too many missing cells, distorted
structures for the organ to function adequately?

41. Focus of Tissue Engineering Pathology
 The focus of tissue engineering pathology will shift to
the question: “Is this organ structurally intact enough to
function safely and adequately in the recipient?” Using
the kidney as an example, the specific questions
become: (Images by Korey Fung)
 2. Are there too many cells in the wrong places (e.g.
podocytes in the interstitium)

42. Focus of Tissue Engineering Pathology
 (Images by Korey Fung)
 3. Are there missing/distorted structural elements that
represent a risk to the patient? (missing loops of Henle
causing lethal polyuria)

43. Focus of Tissue Engineering Pathology
 Using the kidney as an example, the specific questions
become:
 4. Is there too much endothelial disruption
for the organ to be properly perfused?
 5. What are the risks of neoplastic transformation?
 Classification categories should be not one-off, but
reproducible, generalizable.
 Tissue engineering pathology has been up to now
really dull, since most reports were of scaffolds with no
inflammatory reaction "Move along, nothing to see
here" pathology, but from today becomes really
exciting with novel morphological changes and lives
hanging in the balance!

51. Acceptance. Share power. The AIs will not all be under
our control. They will compete and cooperate with us
just like other people, except with greater diversity and
Asymmetries We need to set up mechanisms (social,
legal, political, cultural) to ensure that this works out
well Inevitably, conventional humans will be less
important. Step 1: Lose your sense of entitlement
Step 2: Include AIs in your circle of empathy
Thought provoking for us all!
