"This reference work presents the origins of cells for tissue engineering and regeneration, including primary cells, tissue-specific stem cells, pluripotent stem cells and trans-differentiated or reprogrammed cells. There is particular emphasis on current understanding of tissue regeneration based on embryology and evolution studies, including mechanisms of amphibian regeneration. The book covers the use of autologous versus allogeneic cell sources, as well as various procedures used for cell isolation and cell pre-conditioning , such as cell sorting, biochemical and biophysical pre-conditioning, transfection and aggregation. It also presents cell modulation using growth factors, molecular factors, epigenetic approaches, changes in biophysical environment, cellular co-culture and other elements of the cellular microenvironment. The pathways of cell delivery are discussed with respect to specific clinical situations, including delivery of ex vivo manipulated cells via local and systemic routes, as well as activation and migration of endogenous reservoirs of reparative cells. The volume concludes with an in-depth discussion of the tracking of cells in vivo and their various regenerative activities inside the body, including differentiation, new tissue formation and actions on other cells by direct cell-to-cell communication and by secretion of biomolecules."

"Cell and tissue engineering” introduces the principles and new approaches in cell and tissue engineering. It includes both the fundamentals and the current trends in cell and tissue engineering, in a way useful both to a novice and an expert in the field. The book is composed of 13 chapters all of which are written by the leading experts. It is organized to gradually assemble an insight in cell and tissue function starting form a molecular nano-level, extending to a cellular micro-level and finishing at the tissue macro-level. In specific, biological, physiological, biophysical, biochemical, medical, and engineering aspects are covered from the standpoint of the development of functional substitutes of biological tissues for potential clinical use. Topics in the area of cell engineering include cell membrane biophysics, structure and function of the cytoskeleton, cell-extracellular matrix interactions, and mechanotransduction. In the area of tissue engineering the focus is on the in vitro cultivation of functional tissue equivalents based on the integrated use of isolated cells, biomaterials, and bioreactors. The book also reviews novel techniques for cell and tissue imaging and characterization, some of which are described in detail such as atomic force microscopy"

"Osteoartritis merupakan penyakit kronis yang ditandai dengan kemunduran tulang rawan dan menyebabkan kekakuan, nyeri, dan gangguan pergerakan. Strategi rekayasa jaringan tulang menggunakan perancah dapat menjadi alternatif yang menjanjikan untuk regenerasi jaringan tulang yang rusak. Penelitian ini bertujuan untuk fabrikasi dan karakterisasi perancah dengan material chitosan (CS), hyaluronic acid (HA), hydroxyapatite (Hap) dengan kombinasi penambahan graphite (Gr), graphene oxide (GO), dan multiwalled carbon nanotube (MWNCT) untuk aplikasi rekayasa jaringan tulang. Dalam penelitian ini, dilakukan sintesis GO dan fungsionalisasi kimia dari material Gr dan MWNCT. Fabrikasi perancah dilakukan dengan metode freeze drying. Seluruh kelompok perancah dilakukan karakterisasi SEM dan FTIR, uji tekan dan porositas, uji swelling, wettability, dan laju degradasi. Fabrikasi perancah dibagi menjadi empat kelompok yaitu CS/HA/HAp, CS/HA/HAp/GO, CS/HA/HAp/f-Gr, dan CS/HA/HAp/f-MWNCT dengan ukuran diameter 1 cm, tinggi 1,5 cm, dan luas permukaan luas permukaan 4,71-6,28 cm2. Keseluruhan perancah memiliki ukuran pori yang bervariasi dan terdistribusi pada permukaan. Berdasarkan hasil FTIR, perancah mengandung gugus fungsi O-H, C=O, C-O-C, amida I, amida II, dan fosfat (PO43-). Pada uji kekuatan tekan, keseluruhan perancah memiliki CS/HA/HAp memiliki kekuatan tekan dan young modulus yang serupa dengan cancellous bone sebesar 5,76-6,14 MPa dan 3,95-471 MPa.

Osteoarthritis is a chronic disease characterized by the deterioration of cartilage and causes stiffness, pain, and impaired movement. The bone tissue engineering strategy using scaffolds can be a promising alternative for the regeneration of damaged bone tissue. This study aims to fabricate and characterize scaffolds with chitosan (CS), hyaluronic acid (HA), hydroxyapatite (Hap) with a combination of addition of graphite (Gr), graphene oxide (GO), and multiwalled carbon nanotubes (MWNCT) for tissue engineering applications. In this study, GO synthesis and chemical functionalization of Gr and MWNCT materials were carried out. Scaffolding was done by freeze drying method. All groups of scaffolds were characterized by SEM and FTIR, compressive and porosity tests, swelling, wettability, and rate of degradation tests. Scaffolding was divided into four groups, namely CS/HA/HAp, CS/HA/HAp/GO, CS/HA/HAp/f-Gr, and CS/HA/HAp/f-MWNCT with a diameter of 1 cm, height 1, 5 cm, and a surface area of ​​4.71-6.28 cm2. The entire scaffold has varying pore sizes and is distributed over the surface. Based on the results of FTIR, the scaffold contains functional groups O-H, C=O, C-O-C, amide I, amide II, and phosphate (PO43-). In the compressive strength test, all scaffolds having CS/HA/HAp had similar compressive strength and young modulus with cancellous bone of 5.76-6.14 MPa and 3.95-471 MPa. Scaffolds have porosity rates in the range of 13.8-86.6%. Scaffolds have good wetability with a percentage range of 726-1069%. The swelling ratio of the scaffolds was in the range of 25.2-39.3%. The rate of degradation of the scaffold was quite controlled with a range of 16.7-35.5%. Based on all the characteristic results, the CS/HA/HAp scaffold with the addition of GO was the strongest candidate as the ideal scaffold in this study. The GO scaffold has characteristics that are between the control scaffold and the f-MWNCT/f-Gr scaffold."
