Molecular‐Scale Tuning of Low‐Molecular‐Weight Gelators Controls Supramolecular Assembly and Directs Human Mesenchymal Stem Cell Growth

Angewandte Chemie, EarlyView.
Chemistry in charge of biology! Simple low‐molecular‐weight gelators, with minor modifications in molecular structure, self‐assemble differently and can also co‐assemble when simultaneously triggered. This creates a family of gels with different properties that direct the growth of stem cells in different ways.
