Abstract
The authors report on a mild, label-free, and fast method for the separation of human umbilical vein endothelial cells (HUVEC), which are relevant cells, whose use is not limited to studies of endothelial dysfunction, from cocultures with macrophages to afford HUVEC in ≈100% purity. Poly(di(ethylene glycol)methyl ether methacrylate) (PDEGMA) brushes with a dry thickness of (5 ± 1) nm afford the highly effective one-step separation by selective HUVEC detachment, which is based on the brushes' thermoresponsive behavior. Below the thermal transition at 32 °C the brushes swells and desorbs attached proteins, resulting in markedly decreased cell adhesion. Specifically, HUVEC and macrophages, which are differentiated from THP-1 monocytes, are seeded and attached to PDEGMA brushes at 37°C. After decreasing the temperature to 22°C, HUVEC shows a decrease in their cell area, while the macrophages are not markedly affected by the temperature change. After mild flushing with a cell culture medium, the HUVEC can be released from the surface and reseeded again with ≈100% purity on a new surface. With this selective cell separation and removal method, it is possible to separate and thereby purify HUVEC from macrophages without the use of any releasing reagent or expensive labels, such as antibodies.

On-Demand Cell Sheet Release with Low Density Peptide-Functionalized Non-LCST Polymer Brushes. Macromol Biosci 2023; 23:e2200472.

Abstract
Cell sheet harvesting offers a great potential for the development of new therapies for regenerative medicine. For cells to adhere onto surfaces, proliferate, and to be released on demand, thermoresponsive polymeric coatings are generally considered to be required. Herein, an alternative approach for the cell sheet harvesting and rapid release on demand is reported, circumventing the use of thermoresponsive materials. This approach is based on the end-group biofunctionalization of non-thermoresponsive and antifouling poly(2-hydroxyethyl methacrylate) (p(HEMA)) brushes with cell-adhesive peptide motifs. While the nonfunctionalized p(HEMA) surfaces are cell-repellant, ligation of cell-signaling ligand enables extensive attachment and proliferation of NIH 3T3 fibroblasts until the formation of a confluent cell layer. Remarkably, the formed cell sheets can be released from the surfaces by gentle rinsing with cell-culture medium. The release of the cells is found to be facilitated by low surface density of cell-adhesive peptides, as confirmed by X-ray photoelectron spectroscopy. Additionally, the developed system affords possibility for repeated cell seeding, proliferation, and release on previously used substrates without any additional pretreatment steps. This new approach represents an alternative to thermally triggered cell-sheet harvesting platforms, offering possibility of capture and proliferation of various rare cell lines via appropriate selection of the cell-adhesive ligand.

Application of the water-insoluble, temperature-responsive block polymer poly(butyl methacrylate-block-N-isopropylacrylamide) for pluripotent stem cell culture and cell-selective detachment. J Biosci Bioeng 2022; 133:502-508. [PMID: 35246394 DOI: 10.1016/j.jbiosc.2022.02.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2021] [Revised: 02/04/2022] [Accepted: 02/07/2022] [Indexed: 11/21/2022]
Abstract
Induced pluripotent stem (iPS) cells have been widely studied in regenerative medicine, pathology modeling, and drug screening. Stable mass culture of iPS cells is essential for these applications. iPS cells can spontaneously differentiate into other cells during culture, and removal of these differentiated cells is necessary. Herein, a cost-effective culture method suitable for mass culture and a detailed analysis of the selective detachment of iPS cells are presented. A simple method for coating the water-insoluble thermoresponsive polymer poly (butyl methacrylate-block-N-isopropylacrylamide) on commercially available polystyrene dishes was employed. Analysis of the effects of the polymer composition, coating thickness, and surface structure on iPS cell culture/detachment showed that a coating thickness of approximately 10-40 nm using a polymer with a high poly (N-isopropylacrylamide) content was suitable for iPS cell detachment. Moreover, an interesting change in surface morphology was observed following temperature variation, thereby affecting laminin adsorption. Second, selective detachment in cocultures of iPS cells and differentiated cells enabled collection of iPS cells with more than 98% purity. Finally, long-term iPS cell culture was conducted using temperature-responsive cell detachment. Overall, long-term maintenance-free culture of iPS cells was possible without manual removal of differentiated cells.
