MSC after in vivo aggregation show a favorable RNA expression profile for the treatment of colitis. MSC spheroids showed high expression of Ki-67 and low levels of apoptotic marker cleaved caspase-3. Locally applied MSC and MSC spheroids are both able to ameliorate DSS-induced colitis and show similar clinical effects, including improvement in the macro and microscopic IBD score. The gene discussed is MKI67; the disease is inflammatory bowel disease.
