Abstract
Described herein are aptamers that bind to the transferrin receptor (e.g., CD71) and can be used, in part, for depleting transferrin receptor-expressing cells from a population of therapeutic cells. These aptamer compositions can be used in methods for isolating and/or enriching cells expressing CD71 or depleting cell populations of cells expressing CD71, including for example, tumor cells. Further provided are methods of using the aptamers or cell populations generated using them in the methods disclosed herein for therapies and/or drug delivery.

A composition comprising an aptamer that selectively binds to human CD71, wherein the aptamer comprises a sequence comprising SEQ ID NO:
- 32, wherein the aptamer can further comprise a number (N) of nucleotides at each end wherein each nucleotide is selected independently, and wherein each N comprises from 3 nt to 40 nt, from 3 nt to 30 nt, from 3 nt to 20 nt, or from 3 nt to 10 nt.
