Abstract

The present disclosure relates to cellular compositions that are modified to introduce a nucleic acid or vector expressing the same. Such compositions may be used to deliver nucleic acid to a target cell and treat disease such as cancer.

Claims (10)

1 . A method of treating a cancer in a subject, the method comprising administering to the subject a composition comprising mesenchymal precursor cells (MPCs) or mesenchymal stem cells (MSCs), wherein said MPCs or MSCs comprise an siRNA to KRAS G12D and contact target cancer cells in the subject, whereby the MPCs or MSCs form gap junctions with the contacted target cancer cells, and wherein said cancer comprises an oncogenic G12D mutation in KRAS.

2 . The method of claim 1 , wherein the composition comprises MPCs.

3 . The method of claim 2 , wherein the MPCs express tissue non-specific alkaline phosphatase (TNAP).

4 . The method of claim 1 , wherein the cancer is prostate cancer.

5 . The method of claim 1 , wherein the cancer is a pancreatic cancer or a colorectal cancer.

6 . The method of claim 1 , wherein the MPCs or MSCs are culture- expanded.

7 . The method of claim 1 , wherein the MPCs or MSCs are derived from pluripotent cells.

8 . The method of claim 1 , wherein the target cancer cells are non- syncytial cancer cells.

9 . The method of claim 1 , wherein the target cancer cells are syncytial cells.

10 . The method of claim 1 , wherein the MPCs or MSCs express a viral vector.
