All have radially symmetrical, mainly beetle-pollinated flowers that lack differentiation between the outer and inner floral whorls (sepals and petals).
With the advent of immunohistochemistry and electron microscopy, it has become apparent that GISTs may have myogenic features, neural attributes, and characteristics of both muscle and nerve or may lack differentiation [3].
Because of this lacking differentiation, karyotyping (microscopic analysis of the chromosomes of an individual) can be employed to distinguish the two.
To test this hypothesis, hMSC were incubated in propagation media lacking differentiation stimuli and miRNA levels were altered.
For Ragnerudsjön Lake, mtDNA showed significant differentiation as only 3 of 21 ND2 haplotypes were shared, nDNA haplotypes lacked differentiation as there were only four unique haplotypes from a total of nine closely related haplotypes.
All proliferating vessels had delicate walls and small lumens and lacked differentiation into arterial and venous vessels.
Aggressive tumor cells typically lack differentiation markers of the sympathetic nervous system, similar to the neural crest progenitors (Pietras et al., 2008).
However, at local recurrence eight months later, areas of a cartilaginous tumor were intermingled with an anaplastic sarcoma lacking differentiation, indicating dedifferentiated chondrosarcoma.
Embryonic mammary epithelial cells are an immature progenitor cell population, lacking differentiation markers, which is reflected in their very distinct genetic profiles when compared with those of their postnatal descendents.
