Stem cells (SCs) are a class of cells with unique capacity for self-renewal and multi-lineage differentiation [1]. There are various different types of SCs based on their organizational origin: bone marrow-derived SCs, umbilical cord-derived SCs, adipose tissue-derived SCs (AdSCs), embryo-der...
Most animals protect themselves from the sun with fur.大多数动物用毛皮来防晒。 What we did in our ancestry.(n.祖先;血统)was to produce more permanent(adj.永久的) natural coloring in our skin cells.我们祖先所做的是在我们的皮肤细胞中产生更持久的天然色素。 This was really an important in hum...
Mast cells or basophils play a central role in many diseases such as allergy, bronchial asthma, and parasitic infection. Both types of cells express the high-affinity immunoglobulin E (IgE) receptor FcεRI on their surfaces. Stimulation by various antigens activates cells sensitized with IgE. Ac...
Cellularized skin substitutes with biomimetic cutaneous structures, in particular, exhibit superior healing and regeneration due to the synergistic effects of autologous cells and bioactive scaffolds (primarily degradable collagen) [6,7]. While these cellularized biomimetic skin substitutes provide a ...
These findings show that the signaling feedback between the tumor and stromal cells plays a critical role in controlling the tumor plasticity. This discovery will lead to a novel paradigm in the development of cell differentiation therapy for the treatment of various aggressive types of solid ...

In contrast to conventional 3D printing, 3D bio-printing is more complex in terms of the selection of materials, cell types, growth/differentiation factors, and sensitivity of the living cells construction. A typical 3D bio-printing process consists of the pre-processing, processing and post-...
