Abstract
The present disclosure is based on the discovery that cells enriched with mitochondria are useful for treating diseases and disorders. The present invention provides methods of identifying or detecting such cells enriched with exogenous mitochondria. Specifically, the identification or detection of mitochondria-enriched cells is determined by utilization of a substrate such as tryptamine. This includes determining levels of MonoAmine oxidase A (MAO-A), Mono Amine oxidase-B (MAO-B), glycerol-3-phosphate dehydrogenase or a combination thereof. The present invention also provides kits for the identification or detection of mitochondria-enriched cells.
Claims25
A method of determining enrichment of a cell with exogenous mitochondria comprising:
- a) contacting the cell with a metabolic substrate;
- and
- b) determining electron transfer in the cell following contacting with the metabolic substrate.
(canceled)
8-9. (canceled)
(canceled)
The method of claim 29, wherein the cells are selected from the group consisting of stem cells, progenitor cells or bone marrow derived stem cells, pluripotent stem cells, embryonic stem cells, induced pluripotent stem cells, mesenchymal stem cells, hematopoietic stem cells, hematopoietic progenitor cells, myeloid progenitor cells, lymphoid progenitor cells, megakaryocytes, erythrocytes, mast cells, myoblasts, basophils, neutrophils, eosinophils, monocytes, macrophages, natural killer (NK) cells, small lymphocytes, T lymphocytes, B lymphocytes, plasma cells, reticular cells, myelopoietic cells, erythropoietic cells and any combination thereof.
The method of claim 29, the cells were enriched by contacting the cells with mitochondria.
The method of claim 29, wherein the MAO-A and/or MAO-B levels are determined by mass spectroscopy.
20-23. (canceled)
The method of claim 29, wherein the cells are enriched with placental mitochondria or mitochondria derived from blood.
26-28. (canceled)
A method of determining enrichment of a cell with exogenous mitochondria comprising
- determining electron transfer after contacting the cell with a metabolic substrate, determining levels of MonoAmine oxidase A (MAO-A) and/or MonoAmine oxidase B (MAO-B) in the cell, and/or determining levels of glycerol-3-phosphate dehydrogenase in the cell, and
- wherein after contacting the cell with a metabolic substrate, cells enriched with mitochondria have increased levels of electron transfer, MonoAmine oxidase A (MAO-A), MonoAmine oxidase B (MAO-B), and/or glycerol-3-phosphate dehydrogenase, as compared with cells that are not enriched with mitochondria.
