The establishment of the first human embryonic stem cell (hESC) line in 1998 conferred new hopes for patients that require replacement therapy, since ESCs can self-renew in maintenance culture and can also be theoretically differentiated into any cell type in the human body using differentiation induction culture methods [1].
Note that the covariates can be theoretically differentiated into three categories: the variables of primary interest (proxies of income and maternal education), socio-economic control variables (child sex, child age and whether the child has older siblings) and our three indices of primary interest reflecting health knowledge and health seeking practices.
From the time of Origen on, the Church Fathers who were familiar with Hebrew differentiated, theoretically at least, the Apocryphal books from those of the Old Testament, though they used them freely.
Theoretically, the constructs cannot be differentiated precisely; for example, teamwork is used as a dimension of organizational culture [ 45], or leadership (in our study, a scale of organizational culture) is also a dimension of teamwork and climate (in this study, an item of teamwork, IPS) is highly associated with culture [ 70].
Because Sinemurian ammonites are less geographically differentiated than earlier Jurassic forms, theoretically there should be more possibilities for large-scale regional stratigraphic correlations.
Human embryonic stem cells (hESCs) theoretically represent an unlimited supply of normal differentiated cells to engineer diseased tissues to regain normal function.
In spontaneous thyroid carcinogenesis however, undifferentiated (anaplastic) carcinomas appear to arise from pre-existing differentiated carcinomas, and this could theoretically occur through further somatic mutation in some unresected Chernobyl-related thyroid carcinomas.
Theoretically, for a cell to become a terminally differentiated cell type, it must undergo all consecutive steps of development to be able to respond to the surrounding differentiation cues.
81 Discriminant validity is the extent to which each factor or subscale is well differentiated and will be supported if theoretically different constructs are not highly intercorrelated.
According to these results, a stepwise evolution via well-differentiated carcinomas could not be excluded theoretically for at least a subgroup of these tumours.
Human embryonic stem cells (hESC) are pluripotent cells that can be propagated in vitro for a long period and represent a theoretically inexhaustible source of precursor cells that could be differentiated into any cell type to study human development or treat debilitating diseases [1] [3].
