MEST Regulates the Stemness of Human Periodontal Ligament Stem Cells by Daigaku Hasegawa, Kana Hasegawa, Hiroshi Kaneko, Shinichiro Yoshida, Hiromi Mitarai, Mai Arima, Atsushi Tomokiyo, Sayuri Hamano, Hideki Sugii, Naohisa Wada, Tamotsu Kiyoshima, Hidefumi Maeda

“…Knockdown of MEST by siRNA in 2-23 cells inhibited the expression of stem cell markers, such as CD105, CD146, p75NTR, N-cadherin, and NANOG; the proliferative potential; and multidifferentiation capacity for osteoblasts, adipocytes, and chondrocytes. On the other hand, overexpression of MEST in 2-52 cells enhanced the expression of stem cell markers and PDL-related markers and the multidifferentiation capacity. …”

Comparison between Intra-Articular Injection of Infrapatellar Fat Pad (IPFP) Cell Concentrates and IPFP-Mesenchymal Stem Cells (MSCs) for Cartilage Defect Repair of the Knee Joint... by Yaguang Han, Haobo Li, Rong Zhou, Jun Wu, Ziye Liu, Huan Wang, Jiahua Shao, Yi Chen, Jun Zhu, Qiwei Fu, Qirong Qian, Yiqin Zhou

“…IPFP-MSCs sprouting from the IPFP cell concentrates were characterized via flow cytometry as well as based on their potential for differentiation into adipocytes, osteoblasts, and chondrocytes. In the rabbit model, cartilage defects were created on the trochlear groove, followed by treatment with IPFP cell concentrates, IPFP-MSCs, or normal saline IA injection. …”

Induced mesenchymal stem cells generated from periodontal ligament fibroblast for regenerative therapy by Hemanathan Vembuli, Sheeja Rajasingh, Patrick Nabholz, Jefferson Guenther, Brian R. Morrow, Margaret M. Taylor, Marziyeh Aghazadeh, Vinoth Sigamani, Johnson Rajasingh, Johnson Rajasingh, Johnson Rajasingh

“…These iMSCs demonstrated trilineage differentiation potential, giving rise to osteocytes, chondrocytes, and adipocytes. The iMSC-derived osteocytes (iOSTs) were homogeneous, patient-specific and showed excellent attachment and growth on commercial collagen-based membranes, highlighting their suitability for bone tissue regeneration applications. …”

Generation of Inducible CRISPRi and CRISPRa Human Stromal/Stem Cell Lines for Controlled Target Gene Transcription during Lineage Differentiation by Li Chen, Kaikai Shi, Weimin Qiu, Lars Aagaard, Moustapha Kassem

“…Human bone marrow stromal/stem cells (hMSCs, also known as the skeletal stem cells or mesenchymal stem cells) are being employed to study lineage fate determination to osteoblasts, adipocytes, and chondrocytes. However, mechanistic studies employing hMSC have been hampered by the difficulty of deriving genetically modified cell lines due to the low and unstable transfection efficiency. …”

Hypoxic Wharton’s Jelly Stem Cell Conditioned Medium Induces Immunogenic Cell Death in Lymphoma Cells by Hao Daniel Lin, Chui-Yee Fong, Arijit Biswas, Ariff Bongso

“…The results showed that hWJSCs grown under normoxic or hypoxic conditions showed no distinct morphological differences in culture and remained positive in trilineage differentiation into adipocytes, osteocytes, and chondrocytes. Hypoxic hWJSCs expressed the mesenchymal stem cell surface markers CD105, CD90, CD73, CD146, and CD108 similar to normoxic hWJSCs but were negative for the hematopoietic markers CD14, CD19, CD34, CD45, CD117, and HLA-DR. …”
