Abstract
E ven a well-designed system can only control stem cell adhesion, release, and differentiation, while other cell manipulations such as in situ labeling and retention in target tissues, are difficult to achieve in the same system. Herein, native ligand cluster-mimicking islands, composed of topologically engineered ligand, anchoring point AuNP, nuclease mimetics Ce IV complexes and magnetic core Fe 3 O 4 , are designed to facilitate comprehensive cell manipulations in a programmable manner. Three islands with different amounts of AuNPs are constructed, which means tunable interligand spacing within a cluster. These nanostructures are chemically coupled to a substrate using DNA tethers. Under tissue-penetrative magnetic field, this integrated system promotes stem cell adhesion, proliferation, mechanosensing, differentiation, detachment, in situ effective magnetic labeling and retention both in vitro and in vivo , offering fascinating opportunities for biomimetic matrix in regenerative medicine.

Abstract
Human adipose-derived stem cells (hADSCs) formed robust cell sheets by engineering the cells with soluble cell adhesive molecules (CAMs), which enabled unique approaches to harvest large area hADSC sheets. As a soluble CAM, fibronectin (FN) (100 pg/ml) enhanced the cell proliferation rate and control both cell-to-cell and cell-to-substrate interactions. Through this engineering of FN, a transferrable hADSC sheet was obtained as a free-stranding sheet (122.6 mm2) by a photothermal method. During the harvesting of hADSC sheets by the photothermal method, a collagen layer in-between cells and conductive polymer film (CP) was dissociated, to protect cells from direct exposure to a near infrared (NIR) source. The hADSC sheets were applied to chronic wound of genetically diabetic db/db mice in vivo, to accelerate 30% faster wound closure with a high closure effect (εwc) than that of control groups. These results indicated that the engineering of CAM and collagens allow hADSC sheet harvesting, which could be extended to engineer various stem cell sheets for efficient therapies.

Abstract
Thermosensitive poly(N-isopropylacrylamide) (PNIPAM)-based substrates have presented great promise in cell sheet engineering. However, non-functionalized PNIPAM cannot be well applied for cell cultivation, due to the low cell adhesion. Herein, to enhance PNIPAM-based substrates and to promote cell proliferation and detachment, a polyhedral oligomeric silsesquioxane (POSS) nanoscale inorganic enhanced agent has been introduced into PNIPAM matrices to construct POSS-containing hybrid hydrogels. The hydrogels were facilely prepared using POSS as a cross-linker via one-pot crosslinking reaction under UV irradiation. The swelling behavior, thermal stability and the mechanical properties of POSS–PNIPAM hybrid hydrogels have been evaluated and they are all dependent on the content of POSS. The in vitro experiment confirms that human amniotic mesenchymal stem cells (hAMSCs) exhibit clearly enhanced adhesion and proliferation on the substrates of POSS–PNIPAM hybrid hydrogels in comparison to the pure PNIPAM hydrogel without POSS. Based on the thermal-responsiveness of PNIPAM, the proliferated cells are easily released without damage from the surface of hybrid hydrogels. Therefore, POSS-enhanced PNIPAM hybrid hydrogels provide a unique approach for harvesting anchorage dependent stem cells. Thermosensitive poly(N-isopropylacrylamide) (PNIPAM)-based substrates have presented great promise in cell sheet engineering.![]()

Abstract
Interfaces between materials and cells play a critical role in cell biomedical applications. Here, a simple, robust, and cost-effective method is developed to fabricate patterned thermoresponsive poly(N-isopropylacrylamide-co-styrene) microgel strips on a polyethyleneimine-precoated, non-thermoresponsive cell-adherent glass coverslip. The aim is to investigate whether cell sheets could be harvested from these cell-adherent surfaces patterned with thermoresponsive strips comprised of the microgels. We hypothesize that if the cell-to-cell interaction is strong enough to retain the whole cell sheet from disintegration, the cell segments growing on the thermoresponsive strips may drag the cell segments growing on the cell-adherent gaps to detach, ending with a whole freestanding and transferable cell sheet. Critical value concerning the width of the thermoresponsive strip and its ratio to the non-thermoresponsive gap may exist for cell sheet recovery from this type of surface pattern. To obtain this critical value, a series of strip patterns with various widths of thermoresponsive strip and non-thermoresponsive gap were prepared using negative microcontact printing technology, with COS7 fibroblast cells being used to test the growth and detachment. The results unraveled that COS7 cells preferentially attached and proliferated on the cell-adherent, non-thermoresponsive gaps to form patterned cell layers and that they subsequently proliferated to cover the microgel strips to form a confluent cell layer. Intact COS7 cell sheets could be recovered when the width of the thermoresponsive strip is no smaller than that of the non-thermoresponsive gap. Other cells such as HeLa, NIH3T3, 293E, and L929 could grow similarly; that is, they showed initial preference to the non-thermoresponsive gaps and then migrated to cover the entire patterned surface. However, it was difficult to detach them as cell sheets due to the weak interactions within the cell layers formed. In contrast, when COS7 and HeLa cells were cultured successively, they formed the cocultured cell layer that could be detached together. These freestanding patterned cell sheets could lead to the development of more elaborate tumor models for drug targeting and interrogation.
