Research Summary - Tissue culture models


Our group’s research interests are focused on the generation and analysis of cell culture models for brain disorders.


The key areas of interest where we have developed expertise are:

  1. Analysis of cell lines

  2. Generation and analysis of primary neurons from mice and rats

  3. Generation and analysis of human induced pluripotent stem cells


We have developed expertise in the generation and analysis of cells: Generation of stem cells from human hair from patients or mutated using CRIPSR, and differentiation into Neurons and Enterocytes

Viability assays, Analysis of cells (setup, function, composition), Analysis of Biometals


Current projects:

Characterization of cells from patients with Acrodermatitis enteropathica.

Characterization of zinc absorption in enterocytes

Characterization of the role of zinc transporters in neurons
