Human kidney tubuloid cultures represent a valuable in vitro model to study kidney physiology and disease. Tubuloids can be established from kidney tissue (healthy and diseased) as well as urine, the latter representing an easily obtainable and less invasive source of research material.
Here, we present a method to obtain images of the intestine upon laser-induced wounding. By exposing the mouse intestine to a multiphoton laser, the loss of a single or multiple crypt(s) is induced locally. By repeatedly imaging the damaged area over months, the real-time dynamics of intestinal recovery is captured.
