Background/Objective

Research on the respiratory system at the RIKEN laboratory has focused on generating respiratory tissue organoids from mice. To develop an in vitro pathology model, uniform organoids are grown in semi-solid support such as Matrigel®. The spheroids are selected and isolated based on morphological assessment, which is an important requirement in 3D culture. The applicability of CELL HANDLER™ in this spheroid transfer process was evaluated by the RIKEN research group.

Material and Methods

Respiratory tissue organoids were generated in 75% Matrigel® domes in 24-well cell culture plates, subjected to morphological imaging and subsequently harvested directly from the domes using the CELL HANDLER™.

Observations obtained

Organoids which met pre-defined morphological criteria were identified (Fig. 1A), and were picked without contamination with adjacent organoids (Fig. 1B). A representative image of a single organoid transferred to a 96-well cell culture plate is shown in Fig. 2. These data confirmed that only selected organoids were reliably isolated by the CELL HANDLER™. In addition, growth of isolated organoids was observed (data not shown), indicating that no damage was sustained in the transfer process. These data obtained by morphology-based, direct harvesting of organoids from Matrigel® domes demonstrate the applicability of the CELL HANDLER™ in respiratory tissue organoid research.
