A method of growing or maintaining mammalian cells comprises applying a culture of the cells to a surface of a porous inorganic membrane support. The support is preferably a transparent anodic aluminium oxide membrane. The support carrying cells (44) growing or being maintained thereon may comprise a short tube (30) and a disc (32) of the porous inorganic membrane, the disc being sealed round its periphery to the tube adjacent one end thereof. |
