Abstract
Cancer associated fibroblasts (CAF) are known to orchestrate multiple components of the tumor microenvironment, whereas the influence of the whole stromal-fibroblast compartment is less understood. Here, an extended stromal fibroblast signature was investigated to define its impact on immune cell infiltration. The lung cancer adenocarcinoma (LUAD) data set of the cancer genome atlas (TCGA) was used to test whole stroma signatures and cancer-associated fibroblast signatures for their impact on prognosis. 3D cell cultures of the NSCLC cancer cell line A549 together with the fibroblast cell line SV80 were used in combination with infiltrating peripheral blood mononuclear cells (PBMC) for in-vitro investigations. Immune cell infiltration was assessed via flow cytometry, chemokines were analyzed by immunoassays and RNA microarrays. Results were confirmed in specimens from NSCLC patients by flow cytometry or immunohistochemistry as well as in the TCGA data set. The TCGA analyses correlated the whole stromal-fibroblast signature with an improved outcome, whereas no effect was found for the CAF signatures. In 3D microtumors, the presence of fibroblasts induced infiltration of B cells and CD69+CD4+ T cells, which was linked to an increased expression of CCL13 and CXCL16. The stroma/lymphocyte interaction was confirmed in NSCLC patients, as stroma-rich tumors displayed an elevated B cell count and survival in the local cohort and the TCGA data set. A whole stromal fibroblast signature was associated with an improved clinical outcome in lung adenocarcinoma and in vitro and in vivo experiments suggest that this signature increases B and T cell recruitment via induction of chemokines.

Abstract
We established a functional adipose organoid model system for human adipose stem/progenitor cells (ASCs) isolated from white adipose tissue (WAT). ASCs were forced to self-aggregate by a hanging-drop technique. Afterwards, spheroids were transferred into agar-coated cell culture dishes to avoid plastic-adherence and dis-aggregation. Adipocyte differentiation was induced by an adipogenic hormone cocktail. Morphometric analysis revealed a significant increase in organoid size in the course of adipogenesis until d 18. Whole mount staining of organoids using specific lipophilic dyes showed large multi- and unilocular fat deposits in differentiated cells indicating highly efficient differentiation of ASCs into mature adipocytes. Moreover, we found a strong induction of the expression of key adipogenesis and adipocyte markers (CCAAT/enhancer-binding protein (C/EBP) β, peroxisome proliferator-activated receptor (PPAR) γ, fatty acid-binding protein 4 (FABP4), adiponectin) during adipose organoid formation. Secreted adiponectin was detected in the cell culture supernatant, underscoring the physiological relevance of mature adipocytes in the organoid model. Moreover, colony formation assays of collagenase-digested organoids revealed the maintenance of a significant fraction of ASCs within newly formed organoids. In conclusion, we provide a reliable and highly efficient WAT organoid model, which enables accurate analysis of cellular and molecular markers of adipogenic differentiation and adipocyte physiology.

Abstract
BACKGROUND Peripheral nerve decompression surgery can effectively address headache pain caused by compression of peripheral nerves of the head and neck. Despite decompression of known trigger sites, there are a subset of patients with trigger sites centered over the postauricular area coursing. The authors hypothesize that these patients experience primary or residual pain caused by compression of the great auricular nerve. METHODS Anatomical dissections were carried out on 16 formalin-fixed cadaveric heads. Possible points of compression along fascia, muscle, and parotid gland were identified. Ultrasound technology was used to confirm these anatomical findings in a living volunteer. RESULTS The authors' findings demonstrate that the possible points of compression for the great auricular nerve are at Erb's point (point 1), at the anterior border of the sternocleidomastoid muscle in the dense connective tissue before entry into the parotid gland (point 2), and within its intraparotid course (point 3). The mean topographic measurements were as follows: Erb's point to the mastoid process at 7.32 cm/7.35 (right/left), Erb's point to the angle of the mandible at 6.04 cm/5.89 cm (right/left), and the posterior aspect of the sternocleidomastoid muscle to the mastoid process at 3.88 cm/4.43 cm (right/left). All three possible points of compression could be identified using ultrasound. CONCLUSIONS This study identified three possible points of compression of the great auricular nerve that could be decompressed with peripheral nerve decompression surgery: Erb's point (point 1), at the anterior border of the sternocleidomastoid muscle (point 2), and within its intraparotid course (point 3).

Abstract
We explore the status of quiescence, stemness and adipogenic differentiation capacity in adipose stem/progenitor cells (ASCs) ex vivo, immediately after isolation from human subcutaneous white adipose tissue, by sorting the stromal vascular fraction into cell-surface DLK1+/CD34−, DLK1+/CD34dim and DLK1−/CD34+ cells. We demonstrate that DLK1−/CD34+ cells, the only population exhibiting proliferative and adipogenic capacity, express ex vivo the bonafide quiescence markers p21Cip1, p27Kip1 and p57Kip2 but neither proliferation markers nor the senescence marker p16Ink4a. The pluripotency markers NANOG, SOX2 and OCT4 are barely detectable in ex vivo ASCs while the somatic stemness factors, c-MYC and KLF4 and the early adipogenic factor C/EBPβ are highly expressed. Further sorting of ASCs into DLK1−/CD34+/CD24− and DLK1−/CD34+/CD24+ fractions shows that KLF4 and c-MYC are higher expressed in DLK1−/CD34+/CD24+ cells correlating with higher colony formation capacity and considerably lower adipogenic activity. Proliferation capacity is similar in both populations. Next, we show that ASCs routinely isolated by plastic-adherence are DLK1−/CD34+/CD24+. Intriguingly, CD24 knock-down in these cells reduces proliferation and adipogenesis. In conclusion, DLK1−/CD34+ ASCs in human sWAT exist in a quiescent state, express high levels of somatic stemness factors and the early adipogenic transcription factor C/EBPβ but senescence and pluripotency markers are barely detectable. Moreover, our data indicate that CD24 is necessary for adequate ASC proliferation and adipogenesis and that stemness is higher and adipogenic capacity lower in DLK1−/CD34+/CD24+ relative to DLK1−/CD34+/CD24− subpopulations.

Abstract
Background The surgical procedure itself of lengthening the gastrocnemius muscle aponeurosis is performed to treat multiple musculoskeletal, neurological and metabolical pathologies related to a gastro-soleus unit contracture such as plantar fasciitis, Achilles tendinopathy, metatarsalgia, cerebral palsy, or diabetic foot ulcerations. Therefore, the aim of our research was to prove the effectiveness and safety of a new ultrasound-guided surgery-technique for the lengthening of the anterior gastrocnemius muscle aponeurosis, the “GIAR”- technique: the gastrocnemius-intramuscular aponeurosis release. Methods and results An ultrasound-guided surgical GIAR on ten fresh-frozen specimens (10 donors, 8 male, 2 females, 5 left and 5 right) was performed. Exclusion criteria of the donated bodies to science were BMI above 35 (impaired ultrasound echogenicity), signs of traumas in the ankle and crural region, a history of ankle or foot ischemic vascular disorder, surgery or space-occupying mass lesions. The surgical procedures were performed by two podiatric surgeons with more than 6 years of experience in ultrasound-guided procedures. The anterior gastrocnemius muscle aponeurosis was entirely transected in 10 over 10 specimens, with a mean portal length of 2 mm (± 1 mm). The mean gain at the ankle joint ROM after the GIAR was 7.9° (± 1.1°). No damages of important anatomical structures could be found. Conclusion Results of this study indicate that our novel ultrasound-guided surgery for the lengthening of the anterior gastrocnemius muscle aponeurosis (GIAR) might be an effective and safe procedure.

Abstract
Adipose stromal/progenitor cells (ASCs) can differentiate into adipocytes in the course of adipogenesis. This process is governed by systemic factors and signals of the adipose stem cell niche. ASCs isolated from fat tissues and amplified in vitro provide an essential and reliable model system to study adipogenesis. However, current cell culture models routinely grow ASCs on plastic surfaces largely missing niche parameters. In the present communication, we employed human foreskin fibroblasts (HFFs) monolayers as feeder cells for ASCs, which were isolated from human subcutaneous white adipose tissue and amplified in vitro. We found that PPARγ2 and several adipocyte markers were significantly higher expressed in differentiated ASCs growing on feeder layers relative to plastic dishes. Moreover, a significant higher number of adipocytes was generated from ASCs cultured on feeder layer and these adipocytes contained larger fat droplets. Insulin strongly stimulated glucose uptake into adipocytes produced on feeder layer suggesting that these cells show characteristic metabolic features of fat cells. Finally, we show that the HFF feeder layer allows adipogenic differentiation of low-density-seeded ASCs. In conclusion, we demonstrate that the HFF feeder layer increases adipocyte differentiation of ASCs and allows differentiation of low density seeded progenitor cells into functional adipocytes.

Abstract
PURPOSE Inguinodynia or chronic post-herniorrhaphy pain, defined as pain lasting longer than 3 months after open inguinal hernia repair, has become the most important complication after inguinal surgery and therefore compromises the patient´s quality of life. A major reason for inguinodynia might be the lack of neuroanatomical knowledge and suboptimal "management" of the nerves during surgery. METHODS We present a detailed neuroanatomic mapping of the inguinal region by dissection including the most important surgical landmarks with all nerves confirmed by immunohistochemistry, ultrasound guided visualization of the iliohypogastric, ilio-inguinal, and genital branch of the genitofemoral nerve, and a practical (preoperative) algorithm for clinical management. RESULTS Surgically and ultrasonographically relevant structures ("landmarks") in open hernia repair are the anterior-superior iliac spine, pubic tubercle, Camper´s fascia (superficial layer of the superficial abdominal fascia), External oblique aponeurosis, Internal oblique muscle, Transversus abdominis muscle, superficial inguinal ring, external spermatic fascia, cremasteric fascia with cremaster muscle fibers, internal spermatic fascia, cremasteric vein (=external spermatic vein = "blue line"), ductus deferens, pampiniform plexus, inguinal ligament and the inferior epigastric vessels. CONCLUSION A detailed understanding of inguinal anatomy is an indispensable basic requirement for all surgeons to perform inguinal ultrasonography as well as open inguinal hernia repair, avoiding complications, especially postoperative inguinodynia.

Abstract
BACKGROUND The aim of this study was to provide a safe ultrasound-guided minimally invasive surgical approach for a distal tarsal tunnel release concerning nerve entrapments. METHODS AND RESULTS The study was carried out on ten fresh-frozen feet. All of them have been examined by high-resolution ultrasound at the distal tarsal tunnel. The surgical approach has been marked throughout the course of the medial intermuscular septum (MIS, the lateral fascia of the abductor hallucis muscle). After the previous steps, nerve decompression was carried out through a MIS release through a 2.5 mm (± 0.5 mm) surgical portal. As a result, an effective release of the MIS has been obtained in all fresh-frozen feet. CONCLUSION The results of our anatomic study indicate that this novel ultrasound-guided minimally invasive surgical approach for the release of the MIS might be an effective, safe and quick decompression technique treating selected patients with a distal tarsal tunnel syndrome.

Abstract
Background The aim of this study is to provide a safe ultrasound-guided minimally invasive surgical approach for a proximal tarsal tunnel release concerning nerve entrapments. Methods and results The study was carried out on ten fresh-frozen feet. All of them were examined by high resolution ultrasound at the medial ankle region. The surgical approach was marked throughout the course of the flexor retinaculum (laciniate ligament). Once the previous steps were done, the flexor retinaculum release technique was carried out with a 2-mm entry only. As a result, an effective and safe release of the flexor retinaculum was obtained in all fresh-frozen feet. Conclusion The results of our anatomic study indicate that our novel ultrasound-guided minimally invasive surgical approach for the release of the flexor retinaculum might be an effective, safe and quick decompression technique treating selected patients with a proximal tarsal tunnel syndrome.

Abstract
BACKGROUND Increased internal femoral torsion is regarded as a risk factor for patellar instability. Biomechanical investigations confirming this hypothesis are missing. METHODS Eight fresh-frozen cadaver knees were tested on a specially designed simulator. Patellar motion and patellofemoral pressure were evaluated for 0°, 10°, and 20° of increased internal and external femoral torsion with native and with transected medial patellofemoral ligaments used to simulate patellar instability. A regression analysis was used for statistical analysis. FINDINGS In native medial patellofemoral ligaments, there were no significant changes in mean or peak pressures for any torsional states (P≥0.07). At 20° increased internal femoral torsion, there was a significant center of force shift towards the lateral side (P=0.01). Patellar shift was directed laterally at low knee flexion angles up to 30°. Lateral patellar tilt increased significantly at 10° and 20° of increased internal femoral torsion (P≤0.004). In transected medial patellofemoral ligaments, mean pressure (P≤0.005) and peak pressure (P≤0.02) decreased significantly for all torsional states. There was a significantly greater lateral center of force shift with increased internal femoral torsion (P≤0.04). Lateral patellar tilt increased significantly (P<0.001). Patellar shift did not change significantly with increased internal femoral torsion (P≥0.30). INTERPRETATION In a native medial patellofemoral ligament, 20° of increased internal femoral torsion can be regarded as a significant risk factor for patellar instability. With an insufficient medial patellofemoral ligament, 10° of increased internal femoral torsion already represents a significant risk factor.

Abstract
The tumor microenvironment has been identified as a major mediator of immunological processes in solid tumors. In particular, tumor-associated fibroblasts are known to interact with tumor infiltrating immune cells. We describe the influence of fibroblasts and tumor-microenvironment-derived cytokines on the infiltration capacity of CD3+CD8+ cytotoxic T lymphocyte subpopulations using a multicellular 3D co-culture system. 3D tumor microtissues were cultivated using a hanging drop system. Human A549 and Calu-6 cancer cell lines were incubated alone or together with the human fibroblast cell line SV80 for 10 d to form microtissues. On day 10, peripheral blood mononuclear cells (PBMC) were added with or without cytokine stimulation for 24 h. Infiltrating PBMC subpopulations were investigated by flow cytometry. Aggregation of the microtissues and the infiltration of the PBMCs were analyzed by immunohistochemistry, and endogenous cytokine and chemokine expression was analyzed with a multi-cytokine immunoassay. Secretion of chemokines is increased in microtissues consisting of cancer cells and fibroblasts. PBMC infiltrate the whole spheroid in cancer cell monocultures, whereas in co-cultures of cancer cells and fibroblasts, PBMCs are rather localized at the margin. Activated CD69+ and CD49d+ T lymphocytes show an increased microtissue infiltration in the presence of fibroblasts. We demonstrate that the stromal component of cancer microtissues significantly influences immune cell infiltration. The presence of fibroblasts in cancer microtissues induces a shift of T lymphocyte infiltration toward activated T lymphocytes.

Abstract
We describe the heart from a 79-year-old woman with no medical history of cardiac complaints. Her heart shows a regular right coronary artery (RCA) and a variant left coronary artery (LCA) arising from the right sinus of Valsalva. The common stem of the RCA and the LCA is extremely short. The LCA depicts a preinfundibular course with a cranial-anterior loop and reaches the intersection of the anterior interventricular sulcus and the left coronary sulcus, where it divides into the regular branches, the anterior interventricular branch (left anterior descending, LAD) and the circumflex branch (left circumflex, LCx). All further branching resembles a normal distribution with the posterior interventricular branch coming for the RCA. Such a variant LCA is extremely rare with a reported incidence of 0.17 %. However, recognition and angiographic demonstration of such a variation assume the highest priority in a patient undergoing, for instance, direct coronary artery surgery or prosthetic valve replacement.

Abstract
L1 cell adhesion molecule (L1CAM) is a transmembrane molecule belonging to the L1 protein family. It has shown to be a key player in axonal guidance in the course of neuronal development. Furthermore, L1CAM is also crucial for the establishment of the enteric and urogenital organs and is aberrantly expressed in cancer originating in these organs. Carcinogenesis and embryogenesis follow a lot of similar molecular pathways, but unfortunately, comprehensive data on L1CAM expression and localization in human developing organs are lacking so far. In the present study we, therefore, examined the spatiotemporal distribution of L1CAM in the early human fetal period (weeks 8-12 of gestation) by means of immunohistochemistry and in situ hybridization (ISH). In the epithelia of the gastrointestinal organs, L1CAM localization cannot be observed in the examined stages most likely due to their advanced polarization and differentiation. Despite these results, our ISH data indicate weak L1CAM expression, but only in few epithelial cells. The genital tracts, however, are distinctly L1CAM positive throughout the entire fetal period. We, therefore, conclude that in embryogenesis L1CAM is crucial for further differentiation of epithelia.

Abstract
Introduction: Due to the increasing understanding of the mechanisms relevant to the genesis of cancer, we are experiencing a transition from disease to target-oriented therapy. One major hurdle for the development of these targeted therapeutic regimens, however, is the limited availability of predictive in vitro models. The critical challenge is to develop culture models better reflecting in vivo conditions. We present data that highlights the differences of RNA expression of in vivo like 3D microtissues consisting of tumour cells, fibroblasts and two different endothelial cell lines compared to normal 2D cell culture conditions.
Methods: 96-well hanging drop microtiter plates (InSphero AG, Zürich, Switzerland) were applied for the production of 3D mono-, co- and tri-cultures including the human lung cancer cell lines A549 or Colo699 alone or in combination with a human lung fibroblast cell line (SV-80) and either a human umbilical vein endothelial cell line (HUVEC) or the primary human lung microvascular endothelial cell line (HMVEC-L).
In addition, to conventional histology (H&E), tumour endothelial spheroid aggregation was displayed immunohistochemically (IHC) by protein expression of e-cadherin, CD31, von Willebrand factor (vWF) and α-muscle actin (α-SMA).
RNA expression profiling by Affymetrix chip analysis was performed for multicellular 3D microtissues and 2D cultured cell lines.
Results: Endothelial cells aggregated in coherent tube like structures preferentially in the fibroblast consisting core of all microtissues. Furthermore, endothelial cells expressed α-SMA only in microtissues that consisted both of fibroblasts and tumour cells indicating an interaction between these two cell types.
RNA expression profiles revealed a high number of regulated genes in tri-cultures when compared to microtissues only consisting of mono- or co-cultures or to traditional 2D cultivated cells. Regulated genes played an important role either in cell cycle, organelle fission, wound healing and DNA packing.
Interestingly, no difference in the RNA expression was displayed in microtissues containing either immortalized or primary endothelial cells,
Finally, a relation of RNA expression between our cell culture model and patient data was identified.
Conclusion: We demonstrate that cultivation of cells as multicellular microtissues in a 3D environment led not only to a difference in RNA but also in protein expression due to cell - cell interactions. Our data support the importance of performing complex co-culture for investigating tumour stroma interactions.

Abstract
INTRODUCTION The interaction between the immune system and malignant diseases is a proven key target for cancer therapy. We describe an innovative 3D cell culture system comprising both immune and cancer cells to evaluate their interaction and immune cell infiltration to provide an innovative in vitro screening of immunomodulatory agents and biomarkers. METHODS 3D tumor microtissues were cultivated using a hanging drops system. Human non-small-cell lung cancer cell lines were incubated for 7 days to form microtissues. On day 5, peripheral blood mononuclear cells (PBMC) were added with or without interleukin-2 (IL-2) for 24 or 48h. Viability of cancer cells and the infiltrating PBMC subpopulations were investigated by flow cytometry. Aggregation of tumor cells and PBMC and the infiltration of the PBMC into the tumor microtissues were analyzed by immunohistochemistry. Quantification of infiltration was measured by applying the TissueFAXS system. RESULTS Immunohistochemistry revealed PBMC infiltration in all cell lines which increased under IL-2 stimulation. Analysis of infiltrating populations showed both lymphocyte subpopulations and monocytes within the tumor microtissues. In all three co-cultures, CD3+CD8+ and CD3+CD8+CD45R0+CD28+ lymphocytes were increased with IL-2, whereas CD3+CD8+CD45R0-CD28+ PBMCs were decreased with and without IL-2 stimulation. CONCLUSION In summary, we present a novel cell culture system to study the interaction between cancer cells and immune cells in 3-dimensional microtissues. In addition, we report for the first time an in vitro infiltration assay based on 3D microtissues. This model has the potential to provide a tool for ex-vivo drug testing and biomarker screening of immunomodulatory agents.

Abstract
BACKGROUND Isolated tibial plateau impression fractures can be reduced through minimally invasive techniques using balloon inflation and cement augmentation. No evidence exists yet if an additional fixation at all and which method of fixation is necessary in the treatment of these fractures. The purpose of this study was to compare a locking plate and a screw raft for additional fixation after balloon reduction and cement augmentation in isolated tibial plateau impression fractures. Loss of reduction was subsequently analysed without additional fixation. METHODS Lateral tibial plateau impression fractures were created in eight matched pairs of human cadaveric tibiae. Reduction was performed using a balloon inflation system, followed by cement augmentation. Additional fixation was performed with a lateral locking plate or a screw raft (four 3.5-mm screws). Specimens were cyclically loaded at 20-240N, 20-360N and 20-480N. Subsequently, additional fixation was removed and the last cyclic interval (20-480N) repeated. Loss of reduction was assessed by measuring subsidence of the subchondral bone. FINDINGS Fractures treated with plate fixation exhibited less subsidence at higher loads compared with those treated with screw raft fixation (P<0.05). Loss of reduction significantly increased after removal of the additional fixation. INTERPRETATION This experimental study suggests that loss of reduction can be minimised by using locking plate fixation after balloon reduction and cement augmentation in the treatment of isolated tibial plateau impression fractures.

Abstract
Abstract
Introduction: Metastatic spread and the occurrence of tumour cell resistance to therapeutic interventions can be induced by different molecular processes. Among those, tumour stroma interactions play a crucial role. So far only few cell culture models exist to study these cell processes.
Therefore, we describe the development of a hanging drop technology for 3D culture of primary cells isolated from malignant effusion obtained from cancer patients.
Methods: A 96-well hanging drop microtiter plate (InSphero AG, Zürich, Switzerland) was applied for the 3D cultivation of cells. Primary cells were isolated either from malignant ascites or pleura effusion of cancer patients. Cells were seeded either into 2D cell culture plates or into hanging drops for an incubation period of ten days. Apart from conventional histology (H&E), protein expression was displayed immunohistochemically (IHC) and by flow cytometry. The applied antibodies displayed the expression of e-cadherin, vimentin, Ki67, CD31, CD45, Epcam, Leucine-rich repeat-containing G-protein coupled receptor 5 (Lgr5) and α-smooth muscle actin (α-SMA). In addition, viability of all samples was determined by an AnnexinV/Propidium Iodide staining using flow cytometry.
Results: Microtissue aggregation differed significantly depending on whether the malignant cell effusions displayed expression of Epcam. Effusions consisting of a high number of Epcam positive cells formed solid and viable microtissues. The viability of microtissues remained high (>80%) similar to cells cultivated in 2D cell culture plates. Tumour cells, defined as e-cadherin and Epcam positive by flow cytometry were still detected in microtissues after ten days of incubation in 3D.
Furthermore, endothelial cells, defined as CD31 and Lgr5 positive could also be discriminated in microtissues.
Conclusion: We demonstrate that our method is a promising tool for the generation of tumour microtissues consisting of primary isolated cells from malignant effusions. Therefore, our technology represents a promising method to investigate tumour stroma interactions in an in vitro system that reflects more closely the in vivo environment.

Abstract
Introduction: Different molecular processes lead to metastatic spread and the occurrence of tumor cell resistance to therapeutic interventions. Among them, the stromal compartment of tumors plays a key role. We describe the development of our 3D co-culture to a novel tri-culture model, using non-small cell lung cancer (NSCLC) cell lines in combination with a lung fibroblast and two different endothelial cell lines in a hanging drop technology.
Methods: 96-well hanging drop microtiter plates (InSphero AG, Zürich, Switzerland) were applied for the production of 3D mono-, co- and tri-cultures including the human lung cancer cell lines A549 or Colo699 alone or in combination with a human lung fibroblast cell line (SV-80) and either the human umbilical vein endothelial cell line (HUVEC) or the human lung microvascular endothelial cell line (HMVEC-L). In addition, to conventional histology (H&E, PAS) tumor fibroblast spheroid aggregation was displayed immunohistochemically (IHC) by protein expression of e-cadherin, vimentin, Ki67, CD31 and α-smooth muscle actin (α-SMA). Viability of each cell compartment of the microtissue was determined by a modified AnnexinV/Propidium Iodide staining for flow cytometry.
Results: Endothelial cells aggregated either in small colonies with Colo699 or as single cells mainly in the stromal compartment of A540 microtissues. Simultaneously an up-regulation of vimentin and a downregulation of E-Cadherin was observed in co- and tri-cultures compared to monocultures. Furthermore, Ki67 expression increased significantly from mono- to co- and tri-cultures in both cancer cell lines, indicating a high metabolic activity. In addition, a morphological alteration of A549 tumor cells resembling “signet ring cells” was observed for the first time in both endothelial tri-cultures with a significantly increased glycoprotein expression demonstrated by a Periodic acid-Schiff (PAS) stain.
Conclusion: We demonstrate that our method is a promising tool for the generation of multicellular tumor microtissues and reflects in vivo conditions closer than traditional 2D cell culture. Furthermore, it represents an appropriate alternative method to investigate endothelial cell interactions with tumor and stromal cells.

Introduction We describe a novel 3D co-culture model using non-small cell lung cancer (NSCLC) cell lines in combination with lung fibroblasts. This model allows the investigation of tumour-stroma interactions and addresses the importance of having a more in vivo like cell culture model. Methods Automation-compatible multi-well hanging drop microtiter plates were used for the production of 3D mono- and co-cultures. In these hanging drops the two NSCLC cell lines A549 and Colo699 were cultivated either alone or co-cultured with lung fibroblasts. The viability of tumour spheroids was confirmed after five and ten days by using Annexin V/Propidium Iodide staining for flow-cytometry. Tumour fibroblast spheroid formation was characterized by scanning electron microscope (SEM), semi-thin sections, fluorescence microscope and immunohistochemistry (IHC). In addition to conventional histology, protein expression of E-Cadherin, vimentin, Ki67, fibronectin, cytokeratin 7 and α-smooth muscle actin (α-SMA) was investigated by IHC. Results Lower viability was observed in A549 monocultures compared to co-cultures, whereas Colo699 monocultures showed better viability compared to co-cultures. Ki67 expression varied significantly between mono- and co-cultures in both tumour cell lines. An increase of vimentin and decreased E-Cadherin expression could be detected during the course of the cultivation suggesting a transition to a more mesenchymal phenotype. Furthermore, the fibroblast cell line showed an expression of α-SMA only in co-culture with the cancer cell line A549, thereby indicating a mesenchymal to mesenchymal shift to an even more myofibroblast phenotype. Conclusion We demonstrate that our method is a promising tool for the generation of tumour spheroid co-cultures. Furthermore, these spheroids allow the investigation of tumour-stroma interactions and a better reflection of in vivo conditions of cancer cells in their microenvironment. Our method holds potential to contribute to the development of anti-cancer agents and support the search for biomarkers.

Abstract
Introduction: We describe a novel 3D co-culture method using non-small cell lung cancer (NSCLC) cell lines in combination with a lung fibroblast cell line in the hanging drop technology. This method allows the investigation of tumour-stroma interactions and addresses the importance of having a more in vivo like cell culture model. Compared to other 3D models, it better reflects tumour growth in its microenvironment since no addition of growth factors or artificial extracellular matrix (ECM) substitutes are required.
Methods: 96-well hanging drop microtiter plates (InSphero AG, Zürich, Switzerland) were used for the production of 3D mono- and co-cultures. In these hanging drops the two NSCLC cell lines A549 and Colo699 were cultivated either alone or co-cultured with lung fibroblasts. The viability of tumour spheroids was confirmed after five and ten days by using Annexin V/Propidium Iodide staining for flow-cytometry. Tumour fibroblast spheroid aggregation was displayed either by scanning electron microscope, semi-thin sections, immunofluorescence or by immunohistochemistry (IHC). In addition to conventional histology (H&E), protein expression of e-cadherin, vimentin, Ki67 and α-smooth muscle actin (ASMA) was investigated by IHC.
Results: Lower viability was seen in A549 monocultures compared to co-cultures, whereas Colo699 monocultures showed better viability compared to co-cultures. Ki67 expression varied significantly between mono- and co-cultures in both tumour cell lines. The co-cultivation with fibroblasts led to an increased expression of this protein indicating increased proliferation. Furthermore, a vimentin upregulation and an e-cadherin downregulation could be detected during the course of the cultivation indicating a transition to a more mesenchymal phenotype.
Conclusion: We demonstrate that the hanging drops technology is a promising technique for the generation of tumour spheroid co-cultures. Furthermore, these spheroids allow the investigation of tumour-stroma interactions and a better reflection of in vivo conditions of cancer cells in their microenvironment. Our method holds potential to contribute to the development of anti-cancer agents and support the search for predictive biomarkers.

Abstract
The pelvic floor is characterized by a complex morphology because different functional systems join here. Since a clear understanding of the pelvic floor region is crucial for female pelvic surgery and fundamental mechanisms of urogenital dysfunction and treatment, we here describe the accurate and functional anatomy of important pelvic structures and landmarks, clarify their terminology and point out possible errors or misunderstandings as to their existence.
