Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

SAA/FPR2 Signaling Between Pericentral Hepatocytes and Macrophages Exacerbates Zonated Liver Transplant Injury

Advanced Science, EarlyView.
After liver transplantation, ischemia‐reperfusion injury is more severe in pericentral regions. Multiomic analyses of human grafts and mouse models identify FOXO1 activation in pericentral hepatocytes as an upstream driver of SAA secretion. SAA recruits and activates FPR2+ macrophages, amplifying local inflammation. Amilo‐5MER inhibits SAA bioactivity,

Regeneration of Periodontal Tissues: Guided Tissue Regeneration

Dental Clinics of North America, 2010
The concept that only fibroblasts from the periodontal ligament or undifferentiated mesenchymal cells have the potential to re-create the original periodontal attachment has been long recognized. Based on this concept, guided tissue regeneration has been applied with variable success to regenerate periodontal defects.

Bone regeneration using the principle of guided tissue regeneration

Journal of Clinical Periodontology, 1991
Abstract. The biological principle of “guided tissue regeneration” (GTR) was developed for regenerating periodontal tissues, lost as a result of periodontal disease. This principle was based on the hypothesis that non‐desirable types of tissue cells can be prevented from migrating into a wound by means of a membrane barrier and at the same time giving

Regeneration and enlargement of jaw bone using guided tissue regeneration

Clinical Oral Implants Research, 1990
The purpose of this study was to present the surgical procedures and the clinical results of guided tissue regeneration (GTR) treatment aimed at regenerating local jaw bone in situations where the anatomy of the ridge did not allow the placement of dental implants. 12 patients were selected for ridge enlargement or bony defect regeneration.

Guided tissue regeneration

British Dental Journal, 1991
One of the main goals of periodontal therapy is the predictable regeneration of the periodontium by allowing repopulation of periodontal ligament cells into the wound area after surgery and preventing the colonisation of the exposed root surface with epithelial, gingival, and bone cells.

Guided Tissue Regeneration in Mucogingival Surgery

Journal of Periodontology, 1993
The use of expanded polytetrafluoroethylene (ePTFE) membranes in the treatment of mucogingival problems such as gingival recession, has been recently described. The major issues raised dealt with creating and maintaining space under the membrane and designing a flap that could be coronally positioned and at the same time capable of maintaining a good ...

Guided Tissue Regeneration in Periapical Surgery

Journal of Endodontics, 2010
Tissue regeneration by using membrane barriers and bone grafting materials in periapical surgery is an example of tissue engineering technology. Membrane barriers and/or bone grafts are often used to enhance periapical new bone formation. However, the periapical tissues also consist of the periodontal ligament (PDL) and cementum.

Guided Tissue Regeneration With Dentin Biomodification

Journal of Periodontology, 1993
This study was undertaken to provide histologic observations on the effectiveness of citric acid and tetracycline HCl root surface demineralization when used in conjunction with guided tissue regeneration (GTR) procedures. Eight beagle dogs with naturallyoccurring periodontitis were initially treated with scaling and root planing.
