Evaluación de líneas tropicales de maíz (Zea mays) como fuente de alelos favorables para mejorar híbridos simples élites.

open access: yesAgronomía Mesoamericana, 2005
Progenitores de tres híbridos simples fueron cruzados con 23 líneas con el propósito de identificar líneas donantes para mejorar el rendimiento de grano de AN1 x AN2, SSE232-33-30 x SSE255-18-19 y SSE255-18-19 x M.L.S4-1.

The progenitor of SN 1987 A

open access: yesPublications of the Astronomical Society of the Pacific, 1992
We review evolutionary models for the progenitor of SN 1987A and contront these models with available observational/theoretical constraints. For this purpose, we devise five tests a successful model has to fulfill. These include the three major anomalies of the supernova (the blue color of the progenitor, the ring surrounding it and the progenitor's ...

Erythropoietin, progenitors, and repair [PDF]

open access: yesKidney International, 2007
The erythropoietin-erythropoietin-receptor (EPO-EPO-R) system has recently been identified as an important cellular survival pathway. Its presence has also been demonstrated in the kidney and identified as a therapeutic target to prevent loss of renal function. Part of the protective effects may be related to the action of erythropoietin on endothelial

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
