Introduction: Oral lichen planus (OLP) is an autoimmune disease with uncertain etiopathogenecity and no definitive treatment. Considering the recurrent nature of OLP, finding an adjunctive treatment to minimize the risk of chronicity and recurrence of OLP and to decrease the adverse effects of corticosteroids can be promising. This study aimed to assess the efficacy of a mixture of hyaluronic a...

Vocal fold scars and sulcus cause severe vocal problems, but no optimal treatment has been established. In cases, in which the entire lamina propria is occupied by fibrosis vibratory function completely lost, more powerful regeneration materials should be used, or mucosa totally replaced. Amniotic membrane a scaffold material that rich stem cells growth factors high regenerative effect. It can ...

This procedure describes a method to fabricate a multifaceted substrate to direct nerve cell growth. This system incorporates mechanical, topographical, adhesive and chemical signals. Mechanical properties are controlled by the type of material used to fabricate the electrospun fibers. In this protocol we use 30% methacrylated Hyaluronic Acid (HA), which has a tensile modulus of ~500 Pa, to pro...

INTRODUCTION Tissue scaffolds are an integral part of many tissue-engineering and regenerative therapies, as they provide a 3D support to guide cell growth and facilitate the delivery of biochemicals, nutrients, and cells. Recently, there is growing interest in using naturally derived acellular matrices (ACM) as scaffolds [1]. Unlike synthetic materials, ACMs possess native biomechanical and ma...

A new type of composite 3D biomaterial that provides extracellular cues that govern the differentiation processes of mesenchymal stem cells (MSCs) has been developed. In the present study, we evaluated the chondrogenecity of a biohybrid composed of a calcium carbonate scaffold in its calcite polymorph and hyaluronic acid (HA). The source of the calcite scaffolding is an exoskeleton of a sea bar...

The design and application of hyaluronic acid (HA)-based scaffolds to control cell response and construct ideal tissue engineering products have been of great interest in the past few decades. This review provides an overview of the biological properties of HA to better understand how to engineer a cell-scaffold composite that is qualified in tissue engineering; important tissue engineering app...

Tissue-engineered skin substitutes may be either acellular or cellular. Acellular products (i.e., cadaveric human dermis with cellular material removed) contain a matrix or scaffold composed of materials such as collagen, hyaluronic acid, and fibronectin. Cellular products contain living cells such as fibroblasts and keratinocytes within a matrix. The cells contained within the matrix may be au...
