Macrophages: Subtypes, Distribution, Polarization, Immunomodulatory Functions, and Therapeutics

open access: yesMedComm, Volume 6, Issue 8, August 2025.
Macrophages originate from the yolk sac, fetal liver, and bone marrow, differentiating into two main subtypes: M1‐like (proinflammatory) and M2‐like (anti‐inflammatory). These subtypes exhibit high plasticity, allowing them to transform in response to environmental cues or therapeutic interventions.

Embryogenesis in Myrmicine Ants Combines Features of Short Germ‐Band Development With a Progressive Mode of Segmentation

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 5, Page 284-302, July 2025.
Different insect species exhibit remarkable diversity in the developmental trajectories from fertilized eggs to hatching larvae. For three myrmicine ant species, we observe a novel combination of a developmental features: small embryonic primordia, a mode of embryogenesis termed short/intermediate germ‐band development, and progressive establishment of

Abnormal photoreceptor outer segment development and early retinal degeneration in kif3a mutant zebrafish [PDF]

open access: yes, 2016
Photoreceptors are highly specialized sensory neurons that possess a modified primary cilium called the outer segment. Photoreceptor outer segment formation and maintenance require highly active protein transport via a process known as intraflagellar ...

Dissecting the dynamics of signaling events in the BMP, WNT, and NODAL cascade during self-organized fate patterning in human gastruloids. [PDF]

open access: yes, 2019
During gastrulation, the pluripotent epiblast self-organizes into the 3 germ layers-endoderm, mesoderm and ectoderm, which eventually form the entire embryo.

Morphometric‐Assisted Prediction of Developmental Toxicity Using Stem Cell‐Based Embryo Models in Microwells

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 15, 10 June, 2025.
This proof‐of‐concept study involves high‐throughput teratogenicity screening of compounds using XEn/EpiCs, a 3D stem cell‐based embryo model, within microwells. The term ‘morphotoxicity’ is introduced to complement traditional cytotoxicity assays through automated feature extraction and machine‐learning‐assisted classification of morphologies.

Modeling mammalian gastrulation with embryonic stem cells

open access: yes, 2017
Understanding cell fate patterning and morphogenesis in the mammalian embryo remains a formidable challenge. Recently, in vivo models based on embryonic stem cells (ESCs) have emerged as complementary methods to quantitatively dissect the physical and ...

Signaling Centers Drive Brachyury Dynamics and Lineage Commitment in mESC Aggregates

open access: yesFASEB BioAdvances, Volume 7, Issue 6, June 2025.
We used a mouse embryonic stem cell aggregate model to compare the use of Chiron and BMP4 signaling as pulses (applied to the whole aggregate) or signaling centers (applied to part of the aggregate). BMP4 as a pulse was shown to drive neural differentiation, with Chiron inhibiting this effect.

Developmental potential of trunk neural crest cells in the mouse [PDF]

open access: yes, 1994
The availability of naturally occurring and engineered mutations in mice which affect the neural crest makes the mouse embryo an important experimental system for studying neural crest cell differentiation.

NF2 is Essential for Human Endoderm Development

open access: yesAdvanced Science, Volume 12, Issue 17, May 8, 2025.
This study demonstrates that NF2, moesin‐ezrin‐radixin like (MERLIN) tumor suppressor (NF2) is essential for human endoderm formation. NF2 knockout human induced pluripotent stem cells fail to form endoderm both in vitro and in vivo due to yes‐associated protein 1 (YAP1) nuclear translocation, redirecting differentiation toward myofibroblast‐like cells.

Wnt Inhibition Safeguards Porcine Embryonic Stem Cells From the Acquisition of Extraembryonic Endoderm Cell Fates

open access: yesAdvanced Science, Volume 12, Issue 17, May 8, 2025.
The study reports that Wnt inhibitors safeguard porcine embryonic stem cells (ESCs) from acquiring the extraembryonic endoderm (XEN) lineage, and further develop an efficient strategy to derive XEN cells from ESCs. The XEN cells from ESCs exhibit similar transcriptome and chromatin accessibility features to XEN cells from embryos and contribute to ...
