Papila Apical Dentaria como fuente de Células Madre: Relato del Caso

Revista de Odontopediatria Latinoamericana, 2021
Las células madre mesenquimales (MSCs) son células madre adultas que tienen la capacidad de diferenciarse en varios tipos de células. Una rica fuente de células madre mesenquimales puede ser obtenida de tejidos dentales como la papila apical. El objetivo

Warm temperature modifies cell fates to reduce stomata production in Arabidopsis

New Phytologist, Volume 248, Issue 2, Page 672-689, October 2025.
Summary Stomatal abundance decrease in Arabidopsis triggered by warm temperature is attributed to PIF4‐mediated repression of SPEECHLESS (SPCH) expression. We identified the unknown developmental and transcriptional basis of this adaptive response. We traced stomatal lineages in vivo using cell‐identity marker lines and mutants, quantified epidermal ...

Interactions of rare earth elements with living organisms and emerging biotechnical applications

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1251-1274, September 2025.
Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

Pine‐fungal co‐invasion alters whole‐ecosystem properties of a native eucalypt forest

New Phytologist, Volume 247, Issue 5, Page 2342-2356, September 2025.
Summary Pine‐fungal co‐invasions into native ecosystems are increasingly prevalent across the southern hemisphere. In Australia, invasive pines slowly spread into native eucalypt forests, creating novel mixed forests. We sought to understand how pine‐fungal co‐invasions impact interconnected above‐ and belowground ecosystem characteristics.

Evolution of petal patterning: blooming floral diversity at the microscale

New Phytologist, Volume 247, Issue 6, Page 2538-2556, September 2025.
Summary The flowers of angiosperms are extraordinarily diverse. While most floral variation is visible to the naked eye, this diversity goes beyond the macroscale: Floral organs comprise an underappreciated range of cell types that generate a multitude of patterns across their surfaces and give rise to novel structures.

The sensitivity of reconstructed carbon dioxide concentrations to stomatal preparation methods using a leaf gas exchange model

Applications in Plant Sciences, Volume 13, Issue 1, January-February 2025.
Abstract Premise Mechanistic models using stomatal traits and leaf carbon isotope ratios to reconstruct atmospheric carbon dioxide (CO2) concentrations (ca) are important to understand the Phanerozoic paleoclimate. However, methods for preparing leaf cuticles to measure stomatal traits have not been standardized.
