    Abstract All developing organs need to be connected to both the nervous system (for sensory and motor control) as well as the vascular system (for gas exchange, fluid and nutrient supply). Consequently both the nervous and vascular systems develop alongside each other and share striking similarities in their branching architecture. Here we report embryonic manipulations that allow us to study the simultaneous development of neural crest-derived nervous tissue (in this case the enteric nervous system), and the vascular system. This is achieved by generating chicken chimeras via transplantation of discrete segments of the neural tube, and associated neural crest, combined with vascular DiI injection in the same embryo. Our method uses transgenic chick(GFP) embryos for intraspecies grafting, making the transplant technique more powerful than the classical quail-chick interspecies grafting protocol used with great effect since the 1970s. Chick(GFP)-chick intraspecies grafting facilitates imaging of transplanted cells and their projections in intact tissues, and eliminates any potential bias in cell development linked to species differences. This method takes full advantage of the ease of access of the avian embryo (compared with other vertebrate embryos) to study the co-development of the enteric nervous system and the vascular system.

    Abstract The concept of using two-photon excitation in the NIR for the spatiotemporal control of biological processes holds great promise. However, its use for the delivery of nucleic acids has been very scarcely described and the reported procedures are not optimal as they often involve potentially toxic materials and irradiation conditions. This work prepares a simple system made of biocompatible porous silicon nanoparticles (pSiNP) for the safe siRNA photocontrolled delivery and gene silencing in cells upon two-photon excitation. PSiNP are linked to an azobenzene moiety, which possesses a lysine group (pSiNP@ICPES-azo@Lys) to efficiently complex siRNA. Non-linear excitation of the two-photon absorber system (pSiNP) followed by intermolecular energy transfer (FRET) to trans azobenzene moiety, result in the photoisomerization of the azobenzene from trans to cis and in the destabilization of the azobenzene-siRNA complex, thus inducing the delivery of the cargo siRNA to the cytoplasm of cells. Efficient silencing in MCF-7 expressing stable firefly luciferase with siRNAluc against luciferase is observed. Furthermore, siRNA against inhibitory apoptotic protein (IAP) leads to over 70% of MCF-7 cancer cell death. The developed technique using two-photon light allows a unique high spatiotemporally controlled and safe siRNA delivery in cells in few seconds of irradiation.

    Abstract Background: Metastasis is a complex process which is difficult to study and model. Experimental ingenuity is therefore essential when seeking to elucidate the biological mechanisms involved. Typically, in vitro models of metastasis have been overly simplistic, lacking the characteristic elements of the tumour microenvironment, whereas in vivo models are expensive, requiring specialist resources. Here we propose a pipeline approach for the study of cell migration and colonization, two critical steps in the metastatic cascade.
    Methods: We used a range of extracellular matrix derived contexts to facilitate a progressive approach to the observation and quantification of cell behaviour in 2D, 3D and at border zones between dimensions. At the simplest level, cells were set onto collagen-coated plastic or encapsulated within a collagen matrix. To enhance this, a collagen compression technique provided a stiffened, denser substrate which could be used as a 2D surface or to encapsulate cells. Decellularized tissue from the chorioallantoic membrane of the developing chicken embryo was used to provide a more structured, biologically relevant extracellular matrix-based context in which cell behaviour could then be compared with its in vivo counterpart.
    Results: Cell behaviour could be observed and quantified within each context using standard laboratory techniques of microscopy and immunostaining, affording the opportunity for comparison and contrast of behaviour across the whole range of contexts. In particular, the temporal constraints of the in vivo CAM were removed when cells were cultured on the decellularized CAM, allowing for much longer-term cell colonization and cell-cell interaction.
    Conclusions: Together the assays within this pipeline provide the opportunity for the study of cell behaviour in a replicable way across multiple environments. The assays can be set up and analysed using easily available resources and standard laboratory equipment. We believe this offers the potential for the detailed study of cell migration and colonization of tissue, essential steps in the metastatic cascade. Also, we propose that the pipeline could be used in the wider arena of cell culture in general with the increasingly more complex contexts allowing cell behaviours and interactions to be explored in a stepwise fashion in an integrated way.

    Abstract The development of intrinsic ganglia, comprised of neurons and glia cells that innervate airway smooth muscle, is a recognized component of the growing lung. However, the embryological origin of these neurons and glia is unclear. The lung buds develop as an outgrowth of the foregut, which contains migrating neural crest cells (NCC) that ultimately give rise to the enteric nervous system (ENS) along the entire length of the gut. It has therefore been proposed that the intrinsic ganglia of the lung arise from a subset of NCC that leave the gut and migrate into the lung buds during early development. We have tested this hypothesis using quail-chick interspecies grafting to selectively label the hindbrain-derived neural crest cell population that colonizes the gut. In conjunction with antibody labeling and in situ hybridization, we demonstrate that: (i) lung ganglia arise from vagal NCC that migrate from the foregut into the lung buds; (ii) like ENS precursors, these NCC express the transcription factor Sox10, and the receptors EDNRB and RET; (iii) the co-receptor for RET, GFRalpha1, is expressed in the lung mesenchyme and in ganglia; (iv) ganglia persist within the lung throughout development and contain cells immunopositive for the pan-neuronal markers ANNA-1 and PGP9.5, the inhibitory neurotransmitter NO, as shown by NADPH-diaphorase staining, and the glial marker GFAP.

    Abstract SCG10 (Superior Cervical Ganglia 10, STMN2) is a member of the stathmin family of proteins. Stathmins regulate microtubule dynamics by inhibiting polymerization and promoting their depolymerization. SCG10 is believed to be a neuronal-specific stathmin that is enriched in the growth cones of developing neurons and plays a role in regulating neurite outgrowth. In all species examined so far, SCG10 is expressed in both the CNS and PNS. We have cloned two zebrafish SCG10 homologues and have determined the temporal and spatial expression pattern of both of these genes by RT-PCR and in situ hybridization. RT-PCR shows that both transcripts are expressed maternally and zygotically through at least 5 days. In situ hybridization analysis reveals that both SCG10 orthologues have dynamic, spatial expression patterns that are nearly identical to each other. Initially, these orthologues are expressed in discrete areas of the forebrain, midbrain, and hindbrain, as well as in the anterior and posterior lateral line ganglia and transiently in the spinal cord Rohon-Beard neurons. From 48hpf onwards, the level of expression of both genes increases and becomes mainly restricted to the anterior CNS (the forebrain region, retina, optic tectum, and hindbrain), and to the cranial ganglia. From 72 to 96hpf, SCG10 genes are also expressed in the developing neurons in the gut and in the surrounding intestinal mesenchyme. Our results provide a starting point for future studies that will investigate the in vivo function of SCG10 orthologues in zebrafish neural development.

    Abstract Rhabdomyomas are the most common benign cardiac tumours. They are often associated with tuberous sclerosis and can be diagnosed antenatally and postnatally by echocardiography. Rhabdomyomas tend to regress spontaneously and are not usually operated upon, unless they become obstructive or cause severe arrhythmias. We describe the case of a child with tuberous sclerosis who was admitted for the resection of a subependymal giant cell astrocytoma, in whom cardiac rhabdomyomas in the right ventricular outflow tract were diagnosed. These two kinds of tumours are well known in the setting of tuberous sclerosis.

    Abstract In zebrafish, BMP signaling establishes cell identity along the dorsoventral (DV) axis during gastrulation. Owing to the early requirements of BMP activity in DV patterning, it has been difficult to assign later roles in cell fate specification to specific BMP ligands. In this study, we have taken advantage of two follistatin-like genes (fstl1 and fstl2), as well as a transgenic zebrafish line carrying an inducible truncated form of the BMP-type 1 receptor to study the role of Bmp4 outside of the context of DV specification. Characterization of fstl1/2 suggests that they exert a redundant role as BMP antagonists during late gastrulation, regulating BMP activity in axial mesoderm. Maintenance of appropriate levels of BMP signaling is crucial for the proper development of chordamesoderm, a subset of axial mesoderm that gives rise to the notochord, but not prechordal mesoderm, which gives rise to the prechordal plate. Bmp4 activity in particular is required during a crucial window beginning at late gastrulation and lasting through early somitogenesis to promote chordamesoderm proliferation. In the absence of Bmp4, the notochord precursor pool is depleted, and the notochord differentiates prematurely. Our results illustrate a role for Bmp4 in the proliferation and timely differentiation of axial tissue after DV axis specification.
