Human induced pluripotent stem cells (iPSCs) can give rise to multiple cell types and hold great promise in regenerative medicine and disease modeling applications. The Inventors herein developed a reliable two-step protocol to generate human mammary-like organoids from iPSCs. Non-neural ectoderm cell-containing spheres, referred to as mEBs, were first differentiated and enriched from iPSCs using MammoCult medium. Gene expression profile analysis suggested that mammary gland function-associated signaling pathways were hallmarks of 10-d differentiated mEBs. The Inventors generated mammary-like organoids from 10-d mEBs using 3D floating mixed gel culture and a three-stage differentiation procedure. These organoids expressed common breast tissue, luminal, and basal markers, including estrogen receptor, and could be induced to produce milk protein. These results demonstrate that human iPSCs can be directed in vitro toward mammary lineage differentiation.

A deer lure is applied to a licking branch to attract deer, primarily buck deer, in collecting census data on the population of a deer herd in a given area and in deer hunting. The lure is formulated by surgically removing the left and right pre-orbital tear duct glands from the left and right eyes of a deer. The left and right pre-orbital tear duct glands are mixed together to produce a totally pure pre-orbital gland lure, free of any other product removed from any deer. When applied to a licking branch, the lure is effective in attracting deer year round to the licking branch and is not limited to use during the rut.

The present invention pertains to affinity chromatography isolation and purification of extracellular vesicles (EVs). The EVs of the present invention are engineered to enable highly specific binding to e.g. chromatography matrices, which is highly useful for affinity-based isolation and purification of EVs from complex biological fluids such as cell culture medium or biological fluids.
