Clichy, 28 September 2016 - L'Oréal has been committed to tissue engineering for almost 30 years and holds unique knowledge and expertise in the field of hair biology. With this exclusive research partnership, L'Oréal and Poietis are giving themselves the means to pursue a new scientific challenge: bioprinting a hair follicle, the small organ that produces hair, using a bioprinter. This research partnership offers exciting perspectives at a time when conventional tissue engineering technologies remain limited in terms of the complexity of cell patterns. The laser-assisted bioprinting technology developed by Poietis to produce biological tissue can position cells in 3D with extremely high cellular resolution (on the order of ten microns) and cellular viability (over 95%). This unique bioprinting technology involves successively layering micro-drops of bioinks using a quick scan by a laser beam. The living biological tissue created must then be matured for around 3 weeks before it can be used in tests. The combination of this exclusive technology with L'Oréal's unique expertise in hair biology could ...
