Abstract

Provided herein are placental perfusate, placental perfusate cells, and placenta-derived intermediate natural killer cells, and combinations thereof. Also provided herein are compositions comprising the same, and methods of using placental perfusate, placental perfusate cells, and placenta-derived intermediate natural killer cells, and combinations thereof, to suppress the growth or proliferation of tumor cells, cancer cells, and the like, and to treat individuals having tumor cells.

Claims

1. A method of suppressing the proliferation of tumor cells comprising contacting the tumor cells with human placental perfusate cells.

2. The method of claim 1, wherein the tumor cells are blood cancer cells.

3. The method of claim 1, wherein the tumor cells are solid tumor cells.

4. The method of claim 1, wherein the tumor cells are primary ductal carcinoma cells, leukemia cells, acute T cell leukemia cells, chronic myeloid lymphoma (CML) cells, acute myelogenous leukemia cells, chronic myelogenous leukemia (CML) cells, lung carcinoma cells, colon adenocarcinoma cells, histiocytic lymphoma cells, colorectal carcinoma cells, colorectal adenocarcinoma cells, or retinoblastoma cells.

5. The method of claim 1, wherein said perfusate comprises a culture medium.

6. The method of claim 1, wherein said perfusate has been treated to remove a plurality of erythrocytes.

7. The method of claim 1, wherein said contacting is contacting in vitro.

8. The method of claim 1, wherein said contacting is contacting in vivo.

9. The method of claim 8, wherein said contacting is in a human.

10. The method of claim 1, wherein said plurality of placental perfusate cells are total nucleated cells from placental perfusate.

11. The method of claim 1, wherein said placental perfusate cells comprise at least about 50% CD56⁺ placental cells.

12. A method of suppressing the proliferation of tumor cells comprising contacting the tumor cells with a plurality of CD56⁺, CD16⁻

placental intermediate natural killer (PINK) cells.

13. The method of claim 12, wherein said contacting takes place in vitro.

14. The method of claim 12, wherein said contacting takes place in vivo.

15. The method of claim 14, wherein said contacting takes place in a human.

16. The method of claim 12, wherein said tumor cells are primary ductal carcinoma cells, leukemia cells, acute T cell leukemia cells, chronic myeloid lymphoma (CML) cells, acute myelogenous leukemia cells, chronic myelogenous leukemia (CML) cells, lung carcinoma cells, colon adenocarcinoma cells, histiocytic lymphoma cells, multiple myeloma cells, colorectal carcinoma cells, colorectal adenocarcinoma cells, or retinoblastoma cells.

17. The method of claim 12, wherein said PINK cells are contacted with an immunomodulatory compound in an amount and for a time sufficient for said PINK cells to express detectably more granzyme B than an equivalent number of PINK cells not contacted with said immunomodulatory compound.

18. The method of claim 17, wherein said immunomodulatory compound is lenalidomide or pomalidomide.

19. A method of suppressing the proliferation of tumor cells comprising contacting the tumor cells with combined natural killer cells, wherein said combined natural killer cells comprise natural killer cells isolated from placental perfusate and natural killer cells isolated from umbilical cord blood, and wherein said umbilical cord blood is isolated from the placenta from which said placental perfusate is obtained.

20. The method of claim 19, wherein said contacting takes place in vitro.

21. The method of claim 19, wherein said contacting takes place in vivo.

22. The method of claim 21, wherein said contacting takes place in a human.

23. The method of claim 19, wherein said tumor cells are primary ductal carcinoma cells, leukemia cells, acute T cell leukemia cells, chronic myeloid lymphoma (CML) cells, acute myelogenous leukemia cells, chronic myelogenous leukemia (CML) cells, lung carcinoma cells, colon adenocarcinoma cells, histiocytic lymphoma cells, multiple myeloma cells, colorectal carcinoma cells, colorectal adenocarcinoma cells, or retinoblastoma cells.
