Freshwater ecosystems are threatened by multiple anthropogenic stressors, which might be differentiated into two types: those that reduce biological activity at all concentrations (toxic contaminants), and those that subsidize biological activity at low concentrations and reduce it at high concentrations (assimilable contaminants).
Active or functional L1 elements, which are involved in shaping the human genome, are differentiated into three types depending on where they are inserted into the genome.
However, when the surface ectoderm comes into close contact with the optic vesicle, it promotes retinal phenotypes in these progenitors, which differentiate into six types of retinal neurons and one glial type (Müller glia) during retinal development15,16,17,18,19,20,21,22.
By the process of gastrulation, the embryo differentiates into three types of tissue: the ectoderm, producing the skin and nervous system; the mesoderm, from which develop connective tissues, the circulatory system, muscles, and bones; and the endoderm, which forms the digestive system, lungs, and urinary system.
In the midgut epithelium, long-lived progenitors (intestinal stem cells (ISCs)) divide to self-renew and to give rise to committed progenitors (called enteroblasts (EBs)), which directly differentiate into two types of progeny: absorptive enterocytes (ECs) and enteroendocrine cells (EECs) (Jiang and Edgar, 2012).
Though the eyes of animals are diverse in structure and use distinct optical mechanisms to achieve resolution, eyes can be differentiated into two primary types: single-chambered and compound.
Newspaper coverage can be differentiated into three cluster types: 'benefit of nanotechnology application' (n = 104, 72%), 'benefit and scientific certainty of nanotechnology research' (n = 22, 15%), and 'political discourse about scientific uncertainty and risks' (n = 18, 13%).
The amplified ITS gene from nine isolates was differentiated into three sequence types (S1-S3).
The rpoB sequences obtained from nine isolates were differentiated into five sequence types (R1-R5).
In fact, we demonstrated that c-Photina stem cells can be differentiated into two specific cell types and can be used as source of multiple primary-like cells for Ca2+ functional studies.
