c.Phenotypic Characterisation
d.Developmental Biology Aspects
e.Role of Support Cells (Stroma, Nurse Cells)

3.Utilization of Stem Cells in Biotechnology
a.Concept of the Stem Cell Niche
b.Significance of Culture Media
c.Signals for Differentiation
d.Geometrical Aspects for Cell Seeding and Cell Separation

4.Bioreactors for Stem Cell Cultivation
a.Model of the Classic Long Term Bone Marrow Culture
b.Copying Biological Stem Cell Niches in Bioreactors: Design and Qualification of Materials, Flow Dynamics, Media, 3D Cultures versus 2D
c.Methods to Monitor Culture Development over Time
d.Description of the Desired End Products

5.Needs for Adaptation to Use in Clinical Medicine:

Lehrziel

The Course Participants will
-understand the theoretical background of stem cell biology, and the history of the discovery of primitive hematopoietic as well as hematopoietic stem cells
-know the principles of long term bone marrow culture and its value for analyzing the presence and potency of hematopoetic stem cells
-understand and perform simple flow cytometric analysis of blood cells
-know 2 problems on advancing stem cell transplantation to use of cultured stem cells, which are currently being solved and brought into the clinic.
