PCL microspheres with smaller sizes are phagocyted at rapid rate while larger microspheres could cause inflammation. Homogenization can be regarded as an irreversible process to generate microspheres of particular size range while it still remains as the most common approach for microspheres production. Membrane emulsification technology shows great potential in fine tailoring of microspheres while still holds promising ability for scale-up production. Membranes with uniform large pores and dual hydrophilicity might be capable of the production of large microspheres via emulsification with tailorable size distribution. The aim of this study is to verify the feasibility of PVDF membranes with large pores on the generation of PCL microspheres via the combined crystallization diffusion (CCD) approach. The effect of dope solution concentration and PVDF molecular weights on membrane morphologies and the corresponding microspheres characteristics were investigated. Results showed that concentration of 20\u00a0wt% produced microspheres at desirable size of 24.14\u00a0\u00b5m and the optimal span of 0.53. Microspheres with narrow distribution showed the highest drug loading efficiency of baicalin at 8.42 %. The baicalin loaded PCL microspheres presented gradual release of drug release over 33-day of in vitro testing and significantly improved cell growth rate of 111.67 % as compared to the ones prepared by homogenization approach. The wound healing ability was enhanced after the treatment of baicalin-loaded PCL microspheres as compared to empty loaded PCL microspheres.<\/jats:p>","DOI":"10.1177\/08853282251321259","type":"journal-article","created":{"date-parts":[[2025,2,13]],"date-time":"2025-02-13T23:01:36Z","timestamp":1739487696000},"page":"1143-1155","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Baicalin loaded monodispersed polycaprolactone (PCL) microspheres preparation by polyvinylidene fluoride (PVDF) membrane emulsification for wound healing in dermal fibroblasts"],"prefix":"10.1177","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1503-0037","authenticated-orcid":false,"given":"Wenwei","family":"Zhong","sequence":"first","affiliation":[{"name":"School of Traditional Chinese Medicine, Guangdong Pharmaceutical University, Guangzhou, China"},{"name":"Faculty of Chinese Medicine, Medical Sciences Division, Macau University of Science and Technology, Macau, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiang","family":"Cao","sequence":"additional","affiliation":[{"name":"Sustainable Energy and Environment Thrust, The Hong Kong University of Science and Technology (Guangzhou), Guangzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoran","family":"Zeng","sequence":"additional","affiliation":[{"name":"Guangzhou Vanxx Bioworks Co., Ltd, Guangzhou, China"},{"name":"Guangzhou Bio-green Technology Co., Ltd, Guangzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manqun","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Traditional Chinese Medicine, Guangdong Pharmaceutical University, Guangzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guizhen","family":"Li","sequence":"additional","affiliation":[{"name":"School of Traditional Chinese Medicine, Guangdong Pharmaceutical University, Guangzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia","family":"Xiong","sequence":"additional","affiliation":[{"name":"School of Traditional Chinese Medicine, Guangdong Pharmaceutical University, Guangzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunong","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Third Affiliated Hospital, Beijing University of Chinese Medicine, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liwei","family":"Guo","sequence":"additional","affiliation":[{"name":"Guangzhou Bio-green Technology Co., Ltd, Guangzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Ji","sequence":"additional","affiliation":[{"name":"GBA Institute of Collaborative Innovation, Guangzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,2,13]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.3390\/pharmaceutics12080735"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/adhm.201900764"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1039\/d1bm01846a"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijpharm.2017.12.045"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/dss.0000000000000913"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.3109\/14764172.2014.968586"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.regen.2021.100040"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00266-021-02470-6"},{"key":"e_1_3_4_10_2","doi-asserted-by":"publisher","DOI":"10.5999\/aps.2015.42.2.232"},{"key":"e_1_3_4_11_2","doi-asserted-by":"publisher","DOI":"10.1093\/rb\/rbab042"},{"key":"e_1_3_4_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.colsurfb.2013.08.048"},{"key":"e_1_3_4_13_2","doi-asserted-by":"publisher","DOI":"10.1021\/acscentsci.8b00812"},{"key":"e_1_3_4_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ymben.2018.11.008"},{"key":"e_1_3_4_15_2","doi-asserted-by":"publisher","DOI":"10.3390\/ijms24010329"},{"key":"e_1_3_4_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cclet.2020.03.005"},{"key":"e_1_3_4_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.fbp.2023.04.008"},{"key":"e_1_3_4_18_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12951-024-02494-5"},{"key":"e_1_3_4_19_2","first-page":"127","volume-title":"Methods in Enzymology","author":"Park C-M","year":"2015","unstructured":"Park C-M, Xian M.
