Abstract
Methods for obtaining and preserving target cells using degradable three dimensional matrices are described.
Claims20
A method for preserving freshly isolated target cells from a fluid, cell-containing sample, the method comprising:
- a) providing a fluid, cell-containing sample;
- b) passing the sample through a degradable, three-dimensional matrix, wherein the matrix has a porosity that selectively retains target cells while allowing undesired cells to pass through the matrix;
- and
- c) cryopreserving the matrix and freshly isolated target cells retained by the matrix.

A method for preserving target cells from a fluid, cell-containing sample, the method comprising:
- a) providing a fluid, cell-containing sample from a subject;
- b) passing the sample through a three-dimensional matrix, the matrix comprising an inner core and an outer layer disposed around the inner core, the inner core comprising a non-degradable substrate, the outer layer composed of a degradable polymer and having a porosity that retains target cells;
- and
- c) cryopreserving the matrix and target cells retained by the matrix.
