5. Modelos celulares avan\u00e7ados aplicados \u00e0 redu\u00e7\u00e3o da experimenta\u00e7\u00e3o animal<\/h2>\n
Nos \u00faltimos anos, a comunidade cient\u00edfica consolidou metodologias que substituem total ou parcialmente os ensaios cosm\u00e9ticos tradicionais<\/strong>.<\/a>
\nEstas abordagens assentam em modelos celulares humanos e integram dados in vitro<\/em>, in chemico<\/em> e computacionais para gerar avalia\u00e7\u00f5es mais preditivas.<\/p>\n
Na AINIA, estas metodologias aplicam-se tanto \u00e0 cosm\u00e9tica t\u00f3pica como \u00e0 nutricosm\u00e9tica<\/strong>, permitindo avaliar bioacessibilidade, biodisponibilidade e efic\u00e1cia<\/strong> de compostos bioativos atrav\u00e9s de modelos in vitro<\/em> avan\u00e7ados, contribuindo para reduzir a experimenta\u00e7\u00e3o animal<\/strong>.
