C Rombouts, T Giraud, C Jeanneau, I About
The pulp is a highly vascularized tissue situated in an inextensible environment surrounded by rigid dentin walls, with the apical foramina being the only access. The pulp vascular system is not only responsible for nutrient supply and waste removal but also contributes actively to the pulp inflammatory response and subsequent regeneration. This review discusses the underlying mechanisms of pulp vascularization during tooth development, regeneration, and therapeutic procedures, such as tissue engineering and tooth transplantation...

PURPOSE: Collagen barrier membranes were first introduced to regenerative periodontal and oral surgery to prevent fast ingrowing soft tissues (ie, epithelium and connective tissue) into the defect space. More recent attempts have aimed at combining collagen membranes with various biologics/growth factors to speed up the healing process and improve the quality of regenerated tissues. Recently, a new formulation of enamel matrix derivative in a liquid carrier system (Osteogain) has demonstrated improved physico-chemical properties for the adsorption of enamel matrix derivative to facilitate protein adsorption to biomaterials...

In addition to macrophages, multinucleated giant cells (MNGCs) are involved in the tissue reaction to a variety of biomaterials. Especially in the case of bone substitute materials it has been assumed that the MNGCs are osteoclasts, based on the chemical and physical similarity of many materials to the calcified matrix and the bony environment in which they are used. However, many studies indicate that these cells belong to the cell line of the foreign body giant cells (FBGCs), which are of "inflammatory origin", although they have been shown to possess both a pro- and also anti-inflammatory phenotype...

Mesenchymal stem cells (MSC) from bone marrow and periosteum are known to be heavily involved in fracture repair and bone regeneration is thought to be impaired when the surrounding skeletal muscle is damaged. Recent literature from mouse in vivo models suggest that cells originating from skeletal muscle can occupy a fracture callus during open fracture repair when periosteum is compromised. This systematic review set out to ascertain whether there are MSCs residing in human skeletal muscle and whether cells from human skeletal muscle are capable of forming bone in vitro and in vivo...

The crypt is a minimal functional unit in the intestinal epithelium. This unique structure is maintained by surrounding mesenchymal cells that focally interact with associated epithelial cells. Canonical and non-canonical Wnt ligands enable specific microenvironments localized to each end of the crypt major axis. While canonical Wnt-expressing cells are localized near the crypt bottom where intestinal stem cells reside, non-canonical Wnt-expressing cells are positioned beneath the luminal surface of epithelial cells...

Electrical stimulation (ES) is known to guide the development and regeneration of many tissues. However, although preclinical and clinical studies have demonstrated superior effects of ES on cartilage repair, the effects of ES on chondrogenesis remain elusive. Since mesenchyme stem cells (MSCs) have high therapeutic potential for cartilage regeneration, we investigated the actions of ES during chondrogenesis of MSCs. Herein, we demonstrate for the first time that ES enhances expression levels of chondrogenic markers, such as type II collagen, aggrecan, and Sox9, and decreases type I collagen levels, thereby inducing differentiation of MSCs into hyaline chondrogenic cells without the addition of exogenous growth factors...

Facial peri-implant mucosal recessions represent an increasing complication in implant dentistry and may negatively affect the esthetic outcome and patient satisfaction. The aim of the present paper is to provide a review on the potential causes of facial peri-implant mucosal recessions and to provide a rationale for treatment along with possible treatment options. The available data indicate that soft tissue augmentation around dental implants is possible, but at present there is no evidence demonstrating that the augmented soft tissues are able to influence the peri-implant bone levels (e...

Implant placement in post-extraction sites of single teeth in the esthetic zone has been a topic of great interest in the field of implant dentistry since 1990. Triggered by the development of guided bone regeneration, the concept of immediate implant placement became quite popular in the 1990s. In the past 12 years, however, the dental community has begun to focus increasingly on the esthetic outcomes of post-extraction implant placement and several studies indicated a significant risk for the development of mucosal recessions with immediate implants...

A cytocompatible porous scaffold mimicking the properties of extracellular matrices (ECMs) has great potential in promoting cellular attachment and proliferation for tissue regeneration. A biomimetic scaffold was prepared using silk fibroin (SF)/sodium alginate (SA) in which regular and uniform pore morphology can be formed through a facile freeze-dried method. The scanning electron microscopy (SEM) studies showed the presence of interconnected pores, mostly spread over the entire scaffold with pore diameter around 54~532 μm and porosity 66~94%...

Despite a substantially increased understanding of neuropathophysiology, insufficient functional recovery after peripheral nerve injury (PNI) remains a significant clinical challenge. Nerve regeneration following injury is dependent on Schwann cells, the supporting cells in the peripheral nervous system. Following nerve injury, Schwann cells adopt a pro-regenerative phenotype which supports and guides regenerating nerves. However, this phenotype may not persist long enough to ensure functional recovery. Tissue engineered nerve repair devices containing therapeutic cells that maintain the appropriate phenotype may help enhance nerve regeneration...

Regeneration of traumatic defects in skeletal muscle requires the synchronized behavior of multiple cells that participate in repair. The inflammatory cascade that is rapidly initiated after injury serves as a powerful node at which to guide the progression of healing and influence tissue repair. Here, we examine the role that myeloid cells play in the healing of traumatic skeletal muscle injury, and leverage their pro-regenerative functions using local delivery of the immunomodulatory small molecule FTY720...

To develop a biologically mimetic guided tissue regeneration (GTR) membrane with localized sustained drug release function to prevent infection, coaxial electrospinning technique was conducted to fabricate metronidazole (MNA)-loaded poly (ε-caprolactone) (PCL)/zein core/shell nanofibers. The nanofibers displayed a uniform bead-free round morphology as observed by scanning electron microscopy (SEM), and a core/shell structure as confirmed by transmission electron microscopy (TEM). X-ray diffraction (XRD) and differential scanning calorimetry (DSC) characterizations demonstrated that the MNA was well dispersed in the nanofibers matrix...
