The pivotal challenges in emerging therapies, such as gene therapy, CAR-T/stem cell therapy, immunotherapy, and regenerative medicine, include daunting characterization, manufacturing, and chemistry (CMC), poor quality control (QC), costs, and biosafety. The CLE technology harnesses a paradigm-shifting approach by chemically, physically blebbing desired cells to produce cell-like vesicles that fully replicate the structure and function of the parent cells. The CLE technology achieves significantly higher yield in a substantially shorter time via incredibly simpler concentration and purification processes than conventional extracellular vesicle (EV) method, resulting homogeneous, stable, and economically competitive products. Additionally, all types of cells are subject to the CLE technology with consistently high efficiency.
