Abstract
The invention discloses a methodology for the culture of prostate tissue organoids from mouse and human prostate.
Claims14
A method for culturing prostate organoids, the method comprising:
- a) obtaining a sample of prostate tissue from a subject;
- b) dissociating the sample of prostate tissue;
- c) isolating dissociated prostate epithelial cells from the sample of prostate tissue;
- and
- d) culturing the dissociated prostate epithelial cells in a culture medium comprising basal hepatocyte medium, Matrigel, FBS and ROCK inhibitor;
- wherein if the sample of prostate tissue in step (a) is non-cancerous the dissociated prostate epithelial cells form prostate organoids comprising luminal cells and basal cells, or
- wherein if the sample of prostate tissue in step (a) is cancerous the dissociated prostate epithelial cells form prostate organoids with the same differentiated state as the cancerous prostate tissue sample.

A method for culturing prostate organoids, the method comprising:
- a) obtaining a sample of prostate tissue from a subject;
- b) isolating Castration-Resistant NKx3.1-expressing cells (CARNs) from the sample of prostate tissue;
- c) culturing the CARNs in a culture medium comprising basal hepatocyte medium, Matrigel, FBS and ROCK inhibitor;
- wherein if the sample of prostate tissue in step (a) is non-cancerous the CARNs form prostate organoids comprising luminal cells and basal cells, or
- wherein if the sample of prostate tissue in step (a) is cancerous the CARNs form prostate organoids with the same differentiated state as the cancerous prostate tissue sample.

A method for culturing prostate organoids, the method comprising:
- a) obtaining a sample of prostate tissue from a subject;
- b) dissociating the sample of prostate tissue;
- c) isolating dissociated prostate epithelial cells from the sample of prostate tissue;
- d) contacting the dissociated prostate epithelial cells with a Matrigel solution and plating the dissociated prostate epithelial cells and Matrigel solution in a cell culture support, wherein the Matrigel solution forms a matrix;
- e) providing an overlay layer of liquid culture medium to the matrix formed in (d), wherein the liquid culture medium comprises basal hepatocyte medium, FBS and ROCK inhibitor;
- and
- f) incubating the culture of (e);
- wherein if the sample of prostate tissue in step (a) is non-cancerous the dissociated prostate epithelial cells form prostate organoids comprising luminal cells and basal cells, or
- wherein if the sample of prostate tissue in step (a) is cancerous the dissociated prostate epithelial cells form prostate organoids with the same differentiated state as the cancerous prostate tissue sample.
