Currently, various biomaterials have been applied to promote tissue regeneration through different mechanisms by accommodating cells in three-dimensional (3D) microenvironment (Wang et al., 2010).
Biodegradable scaffolds, which mimic the nature of the bone, play an important role for accommodating cells, controlling cell adhesion and proliferation, and facilitating bone regeneration [2].
In addition to accommodating cell lineage relations during development, our approach has the benefit that it works at single CpG dinucleotide resolution and does not require the spatial aggregation of methylation measurements across the genome.
Tissue engineering scaffolds are highly engineered structures that accommodate cells, facilitate their expression, and resorb to facilitate regeneration of tissue.
Therefore, in tissue engineering, a highly porous 3D matrix (scaffold) is often necessary to accommodate cells and to guide their growth and tissue regeneration in three dimensions.
The ideal candidate should accommodate cells by ensuring them the possibility to reform an extracellular matrix (ECM) and, therefore, to physiologically attach, proliferate, and differentiate [6].
In tissue engineering, biomimetic structures are required to accommodate cells and repair tissue functional, moreover to guide cellular adhesion and growth in three dimensional shapes.
These attempts at an artificial extracellular matrix have the potential to accommodate cells and guide their growth and subsequent tissue regeneration.
To exploit the therapeutic potential of growth factors in tissue regeneration, it is necessary to design a porous scaffold in order to concurrently accommodate cells and release angiogenic factors in a controlled manner.
The chitosan/HA sponge filled in Ti part exhibited highly porous and well-interconnected pore architecture, which is produced to accommodate cells without the need to meet mechanical requirements.
Hence, the materials should be able to accommodate cells with respect to their phenotypes, to allow cell division to the right tissue, to maintain the integrity of the surrounding sane tissue, and eventually use their signaling machinery to serve the development of the appropriate neo-tissue.
