1results about How to "Achieve infiltration" patented technology

The application belongs to the field of biomedical engineering, and discloses a human live mucosa organoid and a construction method and application thereof. The construction of the organoid comprises the following steps: preparing a cell gel compound, filling the cell gel compound into a support, implanting the support into a nude mouse subcutaneously after gelation, and obtaining the human live mucosa organoid after culturing for 1-3 weeks. The application also discloses the application of the organoid in disease research or drug screening. The application constructs a sustainable in-vivo biomimetic air-mucosa gas-liquid interface, realizes the transition of mucosa from an "ex-vivo static model" to an "in-vivo dynamic live system", and realizes the comprehensive evaluation of the curative effect of anti-infection drugs from three dimensions of pathogenic bacteria elimination, inflammation reaction regulation and immune cell recruitment inhibition in application, thereby breaking through the limitation of traditional models that can only evaluate the in-vitro bacteriostatic activity and being more consistent with the actual effect of clinical drug treatment.
