Dr Brian Hendrich
Transcriptional Control of Stem Cell Fate
Department of Biochemistry, University of Cambridge
Brian grew up near Seattle, Washington, and consequently is a consummate coffee snob.
He got his PhD from Stanford University in 1995 working on X chromosome inactivation with Huntington Willard. In 1995 he joined the lab of Adrian Bird at the University of Edinburgh and participated in the discovery and characterisation of a family of methyl-CpG binding proteins in mammals.
In 2001 he obtained a Wellcome Trust Career Development Fellowship to start his own laboratory at the Institute for Stem Cell Research, University of Edinburgh. In 2008 he moved to the Wellcome Trust Centre for Stem Cell Research in Cambridge.
He is currently a Wellcome Trust Senior Research Fellow in the Basic Biomedical Sciences, and Director of the PhD Programme in Stem Cell Biology and Medicine for the Wellcome Trust - Medical Research Council Cambridge Stem Cell Institute.
Embryonic stem (ES) cells hold enormous promise for personalised medicine and drug discovery since they can be maintained indefinitely and are pluripotent; that is they have the potential to form any adult cell type. While pluripotency makes ES cells potentially very useful, it also presents a problem: how do you get them to make the cell type you want, and not one you don't? Differentiation of pluripotent cells is exquisitely organised during normal embryogenesis, but controlling differentiation of stem cells in culture presents a major challenge. Since all cells in an organism are genetically identical, the observable differences in their functions and behaviours come down to which genes they express and which genes they don’t express. Therefore in order to understand how to direct cellular identity, we seek to understand how cells regulate gene expression during differentiation. We also seek to understand how subtle differences in gene expression patterns in seemingly identical cells influence any subsequent differentiation decisions. To do this we focus on how the DNA is packaged in the cell and study the proteins involved in regulating this chromatin packaging. We use biochemistry, genetics, in vitro stem cell culture and manipulation, single cell analyses, genome-wide analyses and collaborate with bioinformaticians and computer programmers to better understand how control of transcription facilitates decision making in stem cells. By understanding how ES cells make different developmental decisions this work will bring the medical promise of stem cells closer to realisation.
Cells of early mammalian embryos have the potential to develop into any adult cell type, and are thus said to be pluripotent. Pluripotency is lost during embryogenesis as cells begin to commit to specific developmental pathways.
The goal of the group is to understand the transcriptional regulatory mechanisms that underpin the ability of a homogeneous population of pluripotent cells to give rise to the massive heterogeneity existing in somatic tissues. To achieve this they are using a combination of biochemistry, genetics, developmental biology, bioinformatics, ES cell manipulation, in vitro differentiation, proteomics, and gene expression analyses.

Plain EnglishEmbryonic stem cells can either make more copies of themselves, or differentiate to form any cell type in the body. How cells make the decision to differentiate, and which cell type to differentiate into, is controlled by gene expression patterns. We are studying how precise control of gene expression allows cells to make these decisions.
