A tissue sample processing system and associated methods is disclosed and described. The tissue sample processing system () can include a microfluidic separating system (). The microfluidic separating system () can include a fluid channel to receive a carrier fluid () and a tissue sample (), and a plurality of outlets. Flow of the carrier fluid () and the tissue sample () in the fluid channel can facilitate segregation of materials in the tissue sample () based on size into a plurality of size fractions, such that each one of the plurality of outlets receives a different size fraction of the materials in the tissue sample. In addition, the sample processing system () can comprise a cryopreservation system () associated with at least one of the plurality of outlets to freeze the material in the tissue sample () associated with the at least one of the plurality of outlets.

Tissue sample processing system and associated methods

A method for separating and enriching sperm from a tissue sample comprises: obtaining a microfluidic separating system having an inlet end and an outlet end, and a membrane filter (e.g., hollow fiber membrane filter) fluidly connected to the outlet end; separating the tissue sample via the microfluidic separating system into a debris fluid volume and a sperm fluid volume; and enriching the sperm fluid volume by removing excess media via the membrane filter. A two-stage tissue sample separation system comprising: a microchannel structure defining a separation fluid channel to form a separation stage; an inlet end of the microchannel structure; an outlet end of the microchannel structure; and a membrane filter fluidly connected to the outlet end for removal of at least a portion of excess media in the tissue sample.
