Abstract:

Selecting and propagating a cell colony of interest from among a plurality of cell colonies carried on a common substrate in culture is carried out by: (a) selecting a cell colony of interest from among the plurality of cell colonies; (b) isolating a cell subset from the cell colony of interest; (c) analyzing (for example, by a destructive analysis) the cell subset isolated from the cell colony of interest to confirm the presence or absence of a desired feature therein; and then (d) propagating the cell colony of interest when the desired feature is present in the cell subset. A micropallet apparatus may include: (a) a substrate; (b) a plurality of discrete arrays formed on the substrate, each of the arrays comprising a plurality of releasable pallets, and (c) a plurality of gap forming regions, wherein the gap forming regions surround the pallets and separate the pallets from one another.

Abstract:

An apparatus for collecting or culturing cells or cell colonies has a common substrate and a plurality of cell carriers releasably connected to the common substrate. The carriers are arranged in the form of an array. The invention employs microcups as the cell carriers. The substrate is preferably free of barriers between the microcups, and in some embodiments the microcups have porous walls. Methods of using the apparatus are also described.

Abstract:

An example system includes a first and second digital device. The first digital device may be configured to provide an interface displaying an image including a depiction of an object, place a bounding shape around the object, and crop contents of the bounding shape to create a portion. The second digital device may be configured to receive the portion, retrieve high-level features and low-level features, apply first Atrous Spatial Pyramid Pooling (ASPP) to the high-level features to aggregate the high-level features as aggregate features, concatenate results to create the aggregate features, up-sample, apply a convolution to the low-level features, concatenate the aggregate features with the low-level features after convolution to form combined features, segment the combined features to generate a polygonal shape outline along outer boundaries of the first object, and provide the first polygonal shape outline to the first digital device for display.
