Targeted Embryonic stem cell Differentiation
TED is a technology that standardizes the differentiation of embryonic stem cells as the unique technology name of S.Biomedics.
Importance of embryonic stem cells
  • Self-renewal
    Able to proliferate infinitely with one cell line
    Stability in the supply of raw materials (stem cells)
  • Pluripotency
    Able to secure specific cell type
    Able to secure intended cell type
  • Cells derived from a single donor
    Prevents deviation of raw materials (stem cells)
    Easy to control the quality
Importance of pluripotency
  • Able to secure specific cell types difficult to be secured

    Nerve cells and nervous system cells are difficult to be obtained from adults. However, through the differentiation of embryonic stem cells, it is possible to secure such cell types that couldn't be secured.

    A fundamental solution in regenerative medicine can be presented by securing cells identical to damaged ones.

OUTLINE

TED technology strictly blocks endodermal and mesodermal differentiation of all embryonic stem cells by controlling two specific signaling pathways (BMP, Activin/Nodal signaling pathway) using two types of small molecules (SB431542, Dorsomorphin). All pluripotent stem cell types including embryonic stem cells can be induced to differentiate consistently and effectively into neural precursor cells by highly effective induction of only the differentiation into the neuroectoderm.

DATA
Differentiation of Neural Precursor Cells

The previously used differentiation methods have shown a wide variation in differentiation yield and the differentiation efficiency was low due to the individual characteristics of each embryonic stem cell line. However, using TED technology, the various differentiation tendencies of each embryonic stem cell line can be overcome and nervous system cells are able to be differentiated from all the embryonic stem cell lines with high efficiency.

Existing nerve cell differentiation yield
  • Embryonic stem cell line 1
  • Embryonic stem cell line 2
  • Embryonic stem cell line 3
  • Embryonic stem cell line 4
  • Embryonic stem cell line 5
  • 0%
  • 20%
  • 40%
  • 60%
  • 80%
  • 100%

Difficult to predict the yield of differentiation into neural precursor cells

Yield of “TED technology” differentiation
  • Embryonic stem cell line 1
  • Embryonic stem cell line 2
  • Embryonic stem cell line 3
  • Embryonic stem cell line 4
  • Embryonic stem cell line 5
  • 0%
  • 20%
  • 40%
  • 60%
  • 80%
  • 100%

Production of highly pure neural precursor cells available from all the embryonic stem cell lines

Expandability

The pipeline can be expanded by differentiation into various nerve subtype-cells after producing neural precursor cells with high efficiency using TED technology.
