Growing two or more different tissues in a single functional organoid is a special challenge that Gouti-Lab has mastered with the generation of neuromuscular organoids. Such organoids enable the study of neuromuscular diseases - where more than one tissue is involved - such as myasthenia gravis. The current project of Dr. Mina Gouti (MDC), Prof. Dr. Carmen Birchmeier (MDC) and Prof. Dr. Nikolaus Rajewsky (MDC/BIMSB) is primarily aimed at improving and accelerating the maturation of the organoid.
