Abstract

Biologically low invasive vessels are filled with biological factors that have the activity of mobilizing specific functional cells in the body. The vessels are indwelled in the body. After specific functional cells are mobilized into the vessels, the vessels are removed from the body to collect functional cell populations mobilized to the vessels. Alternatively, the cells are directly collected from the vessels indwelled in the body.

Claims

1. A method for collecting bone-marrow-derived stem cells from a subject, wherein the method comprises:

(I) implanting for at least 12 hours a vessel that contains a substance of any of (a) to (j) below, completely under the skin in subcutaneous adipose of the subject, to induce stem cells present in the bone marrow of the subject to migrate to the vessel implanted in subcutaneous tissue, wherein, as a result of the presence of the substance, stem cells present in bone marrow of the subject enter the vessel implanted in subcutaneous adipose;

(a) an HMGB1 protein,

(b) a cell that secretes an HMGB1,

(c) an HMGB2 protein,

(d) a cell that secretes an HMGB2,

(e) an HMGB3 protein,

(f) a cell that secretes an HMGB3 protein,

(g) an S100A8 protein,

(h) a cell that secretes an S100A8 protein,

(i) an S100A9 protein,

and (j) a cell that secretes an S100A9 protein,

wherein the vessel is made from a material that is biologically hypoallergenic when implanted into the subject without any of (a) to (j), and wherein the vessel has one closed end to form an area therein to collect the bone-marrow-derived stem cells; and

(II) collecting bone-marrow-derived stem cells from the vessel.

2. The method according to claim 1, wherein the bone-marrow-derived stem cells comprise bone marrow-derived mesenchymal stem cells, bone marrow stromal pluripotent stem cells, and/or bone marrow pluripotent stem cells.

3. The method according to claim 1, wherein the step of collecting bone-marrow-derived stem cells is performed using vacuum aspiration.

4. The method according to claim 1, wherein the vessel is implanted for at least one week.

5. The method according to claim 1, wherein the vessel is implanted for at least 10 days.

6. The method according to claim 1, wherein the vessel is implanted for at most two weeks.

7. The method according to claim 1, wherein the vessel is implanted for 12 hours to two weeks.

8. The method according to claim 1, wherein the vessel is implanted for one to two weeks.

9. The method according to claim 1, wherein the vessel is implanted for 10 days to two weeks.

10. A method for collecting bone-marrow-derived stem cells from a subject, wherein the method comprises:

(I) implanting for at least 12 hours a vessel, that contains a substance of any of (a) to (j) below, completely under the skin in subcutaneous adipose of the subject, to induce stem cells present in the bone marrow of the subject to migrate to the vessel implanted in subcutaneous tissue, wherein, as a result of the presence of the substance, stem cells present in bone marrow of the subject enter the vessel implanted in subcutaneous adipose;

(a) an HMGB1 protein,

(b) a cell that secretes an HMGB1,

(c) an HMGB2 protein,

(d) a cell that secretes an HMGB2,

(e) an HMGB3 protein,

(f) a cell that secretes an HMGB3 protein,

(g) an S100A8 protein,

(h) a cell that secretes an S100A8 protein,

(i) an S100A9 protein, and

(j) a cell that secretes an S100A9 protein,

wherein the vessel is made from a material that is biologically hypoallergenic when implanted into the subject without any of (a) to (j), and wherein the vessel has one closed end to form an area therein to collect the bone-marrow-derived stem cells;

(II) removing the vessel to outside the body from under the skin in subcutaneous adipose of the subject; and

(III) collecting bone-marrow-derived stem cells from the vessel.

11. The method according to claim 10, wherein the bone-marrow-derived stem cells comprise bone marrow-derived mesenchymal stem cells, bone marrow stromal pluripotent stem cells, and/or bone marrow pluripotent stem cells.

12. The method according to claim 10, wherein the step of collecting bone-marrow-derived stem cells is performed using vacuum aspiration.

13. The method according to claim 10, wherein the vessel is implanted for at least one week.

14. The method according to claim 10, wherein the vessel is implanted for at least 10 days.

15. The method according to claim 10, wherein the vessel is implanted for at most two weeks.

16. The method according to claim 10, wherein the vessel is implanted for 12 hours to two weeks.

17. The method according to claim 10, wherein the vessel is implanted for one to two weeks.

18. The method according to claim 10, wherein the vessel is implanted for 10 days to two weeks.

19. A method for collecting bone-marrow-derived stem cells from a subject, wherein the method comprises:

(I) implanting for at least 12 hours a vessel that contains a substance of any of (a) to (j) below, completely under the skin in subcutaneous adipose of the subject, to induce stem cells present in the bone marrow of the subject to migrate to the vessel implanted in subcutaneous tissue, wherein, as a result of the presence of the substance, stem cells present in bone marrow of the subject enter the vessel implanted in subcutaneous adipose;

(a) an HMGB1 protein,

(b) a cell that secretes an HMGB1,

(c) an HMGB2 protein,

(d) a cell that secretes an HMGB2,

(e) an HMGB3 protein,

(f) a cell that secretes an HMGB3 protein,

(g) an S100A8 protein,

(h) a cell that secretes an S100A8 protein,

(i) an S100A9 protein, and

(j) a cell that secretes an S100A9 protein,

wherein the vessel is made from a material that is biologically hypoallergenic when implanted into the subject without any of (a) to (j), and wherein the vessel has one closed end to form an area therein to collect the bone-marrow-derived stem cells; and

(II) collecting bone-marrow-derived stem cells from the vessel, which is still under the skin in subcutaneous adipose of the subject.

20. The method according to claim 19, wherein the bone-marrow-derived stem cells are a bone marrow-derived mesenchymal stem cell, a bone marrow stromal pluripotent stem cell, or a bone marrow pluripotent stem cell.
