While further studies, besides the indirect evidence (see below), are required to confirm whether or not such cells could be functional, trans-differentiated cells with residual parental properties have been observed to acquire the functions of converted lineage [54], [55], [56].
We propose that nucleoplasmin may have acquired the function of SNBP removal after fertilization in many vertebrates because of the appearance and vertical evolution of SNBPs.
These phylogenetic analyses have suggested that RPSA is a ribosomal protein that has acquired the function of laminin receptor during evolution [ 7, 8].
We propose that apart from a role in nutrition of the embryo, the hypoblast/AVE acquired the function of delaying PS formation while repositioning the streak precursor cells to the midline (Stern and Downs, 2012).
Nearly 100% cells acquire the overall functions of serotonergic 1C115-HTT) or noradrenergic (1C11NE) neurons, within 4 or 12 days, respectively.
The capacity of CD8+ T cells expressing ectopic T-bet at physiological levels to acquire the effector functions of producing IFN-γ [ 17] and expressing FasL [ 19] indicates that these known effects of this transcription factor occur independently of the cytokines that normally induce its expression.
Once restricted to the intracellular environment, the opportunities for LGT are diminished, so the likelihood of reversal is low, and the possibility of ever acquiring the functions needed to live in a less specialized environment successfully (i.e. in competition with better equipped organisms) is small.
Initially, feathers were used as insulators or for display, but they have since acquired the additional function of flight devices.
On both Tomasello's and the nativist's view, in other words, the inborn structures responsible for language acquisition will have acquired the biological function of enabling language acquisition: they will be specialized for that purpose.
In addition to acquiring the therapeutic function of FGF-1, the transgenic plants also contained natural, endogeneous, medicinal compounds, such as tanshinone-I, tanshinone-IIA and cryptotanshinone.
