Tribute Lecture at Brawijaya Women & Children Hospital Jakarta 2013 on the topic of the usefulness of human stem cell in dermatology including case reports
2. Why Stem Cells ?
By definition, a stem cell is
characterized by its ability to self-renew
and its ability to trans differentiate
along multiple lineage pathways.
3. What are the unique properties of
all stem cells ?
They are capable of dividing and renewing
themself for long periods
They are unspecialized
They can give rise to specialized cell types
4. DEFINITIONS
Stem cells is a special kind of cell
that has a unique to renew itself
and to give rise to many specialized
cell types (pluripotency)
Contrary to most cells of the body
Stem Cells is uncomitted & remains
uncomitted, until it receives a signal to
develop into a specialized cell
5. What are the unique properties of all stem
cells
Three general properties :
They are capable of deviding and renewing
themself of long periods
They are unspecialized
They can give rise to specialized cell types
6.
7. Stem cells can remain alive in human corpses for at least 17 days
after death, researchers say. Stem cells give rise to all other cells
in the body, a property that ...

25. FROM CELL BASED THERAPY TO “CELL FREE”
BASED THERAPY
Illustration of cell based therapy (Takashi et al., 2007)
26. WHAT IS “CELL FREE” BASED THERAPY?
Illustration of therapeutic effect of stem cells (Tom JB et al., 2011)
27. EPC-CM and EPC transplantation improve blood perfusion in the
rat ischaemic hindlimb with increased capillary density. A. doppler
imaging. B. immunofluorescence
30. Stem cell based therapy
Therapeutic outcome depends
on cells engraftment
Major limitation related to
Alloimmunity reaction
“Cell free” based
therapy
Cell free medium containing
paracrine secretome may
reduce risk of adverse
immunological reaction
31. Xeno- free supplementation system
Human Platelet Lysate (HPL) supplementation
replace Fetal bovine serum (FBS) supplementation
Cell culture manipulation for producing specific
defined “cell free” secretome
32. Hypoxic culture condition for promoting defined
secretome related Hypoxic Inducible Factor gene
pathway induction
33. 3D spheroid culture system for promoting
secretion of specific cytokine
3D spheroid colony (3000-5000
cells/colony)
34. Proteome profiling of cells
secretome
Ultrafiltration of Secretome
Endotoxin &
mycoplasma assay

58. SECRETOME FROM HUVEC (HUMAN UMBILICAL
VEIN ENDOTHELIAL CELLS) for patient Alopecia Areata
with cicatrix, for more than 10 years.
After 1 month
By Indah - 2012
62. Woman, 82 years old, with BASALIOMA in uper os
mandibula for 5 years, extirpation by MOHS surgery, no
sutures, just only using Topical – HUVEC for getting wound
closure for 6 weeks
73. CONCLUSION
Interventions based on stem cells secretome may
replace cell transplantation to enhance therapeutic
tissue regeneration
Cell free strategy seems to b free from the limitations
and problems observed with transplantation of fresh or
in vitro cultured cells
